King Crimson

King Crimson were an English-based progressive rock band formed in 1968 in London. Led by guitarist Robert Fripp, they drew inspiration from a wide variety of music, incorporating elements of classical, jazz, folk, heavy metal, gamelan, blues, industrial, electronic, experimental music and new wave. They exerted a strong influence on the early 1970s progressive rock movement, including on contemporaries such as Yes and Genesis, and continue to inspire subsequent generations of artists across multiple genres. The band has earned a large cult following, especially in the 21st century.

Founded by Fripp, Michael Giles, Greg Lake, Ian McDonald and Peter Sinfield, the band initially focused on a dramatic sound layered with Mellotron, McDonald's saxophone and flute, Giles' complex and polyrhythmic drumming, Fripp's atmospheric guitar sound, and Lake's bass and powerful lead vocals, with gothic lyricism by Sinfield and creative directions by all members of the band. Their debut album, In the Court of the Crimson King (1969), remains their most commercially successful and influential release, with a potent mixture of jazz, classical and experimental music. Following the sudden simultaneous departures of McDonald and Giles (with Lake leaving very shortly afterwards), the next two albums, In the Wake of Poseidon and Lizard (both 1970), were recorded during a period of instability in the band's line-up. A settled band of Fripp, Sinfield, Mel Collins, Boz Burrell and Ian Wallace recorded Islands in 1971, though in mid-1972, Fripp let go of this line-up and changed the group's instrumentation and approach, drawing from European free improvisation and developing ever more complex compositions. With Bill Bruford (formerly of Yes), John Wetton, David Cross and, briefly, Jamie Muir, they reached what some saw as a creative peak on Larks' Tongues in Aspic (1973), Starless and Bible Black (1974), and Red (1974). King Crimson disbanded at the end of 1974.

After seven years of inactivity, King Crimson was recreated in 1981 with another change in musical direction. The new band comprised Fripp, Bruford and two new American members: Adrian Belew, who previously worked with David Bowie, Frank Zappa and Talking Heads, and Tony Levin, a prolific session musician who was noted for his studio and live work with Peter Gabriel. They drew influence from African music, gamelan, post-punk and New York minimalism. This band lasted three years, resulting in the trio of albums Discipline (1981), Beat (1982) and Three of a Perfect Pair (1984). Following a decade-long hiatus, they reformed in 1994, adding Pat Mastelotto, formerly of Mr. Mister, and Trey Gunn for a sextet line-up Fripp called "The Double Trio". The double trio participated in another three-year cycle of activity that included the release of Thrak (1995), and multiple concert recordings. There was a hiatus between 1997 and 2000. Fripp, Belew, Mastelotto and Gunn reunited in 2000 as a more industrial-oriented King Crimson, called "The Double Duo", releasing The Construkction of Light (2000) and The Power to Believe (2003). After a five-year hiatus, the band added Gavin Harrison of Porcupine Tree as a second drummer, with Levin returning in place of Gunn, for a 2008 tour celebrating the 40th anniversary of their 1968 formation.

Following another hiatus (2009–2012), during which Fripp was thought to be retired, King Crimson came together again in 2013; this time as a septet (and, later, octet) with an unusual three-drumkit frontline, and new second guitarist and singer Jakko Jakszyk. This version of King Crimson continued to tour from 2014 to 2021, and released multiple live albums. After the band's final show in 2021, Fripp commented that King Crimson had "moved from sound to silence."

1967–1968: Giles, Giles and Fripp
In August 1967, brothers Michael and Peter Giles, drummer and singer/bassist respectively and pro musicians in working bands since their mid-teens in Dorset, England, advertised for a "singing organist" to join a group they were forming. Fellow Dorset musician Robert Fripp – a guitarist who neither played organ nor sang – responded, and Giles, Giles and Fripp was born. The trio recorded several quirky singles and one eclectic album, The Cheerful Insanity of Giles, Giles and Fripp. They hovered on the edge of success, and even made a television appearance, but were never able to make a commercial breakthrough. Attempting to expand their sound, the three recruited Ian McDonald on keyboards, reeds and woodwinds. McDonald brought along two new participants: his then-girlfriend, former Fairport Convention singer Judy Dyble, whose brief tenure with the group ended when the two split, and lyricist, roadie, and art strategist Peter Sinfield, with whom he had been writing songs – a partnership initiated when McDonald had said to Sinfield (regarding his band Creation), "Peter, I have to tell you that your band is hopeless, but you write some great words. Would you like to get together on a couple of songs?" Fripp, meanwhile, saw Clouds at the Marquee Club in London which spurred him to incorporate classically inspired melodies into his writing, and utilise improvisation to find new ideas. No longer interested in Peter Giles' more whimsical pop songs, Fripp recommended that his old friend, fellow guitarist and singer Greg Lake could join to replace either Peter or Fripp himself. Peter Giles later called it one of Fripp's "cute political moves". According to Michael Giles, his brother had become disillusioned with the band's lack of success and departed before Fripp suggested Lake to fill Peter Giles' position as bassist and singer.

1968–1970: Original line-up and In the Court of the Crimson King
The first incarnation of King Crimson—Fripp, Michael Giles, Lake, McDonald and Sinfield—was formed on 30 November 1968 with rehearsals beginning on 13 January 1969. Sinfield coined the band's name in "a moment of pressured panic". Sinfield had already used the term "crimson king" in a set of lyrics before his involvement with Giles, Giles and Fripp. Sinfield insisted that the name wasn't Beelzebub, prince of demons, and that a "crimson king" was any ruler during whose reign there were "societal rumblings" and "sort of the dark forces of the world". According to Fripp, King Crimson is a synonym for Beelzebub, which is an anglicised form of the Arabic phrase "B'il Sabab", meaning "the man with an aim", to which he related. At this early point, McDonald was the primary composer, with vital contributions from Fripp and Lake, while Sinfield wrote all the lyrics on his own, and also designed and operated the band's unique stage lighting, being credited with "words and illumination" on the album sleeve. Inspired by the Moody Blues, McDonald suggested the group purchase a Mellotron keyboard, and this became a key component of the early Crimson sound. Sinfield described the original Crimson thus: "If it sounded at all popular, it was out. So it had to be complicated, it had to be more expansive chords, it had to have strange influences. If it sounded, like, too simple, we'd make it more complicated, we'd play it in 7/8 or 5/8, just to show off".

King Crimson's first live performance was at the Speakeasy Club in London on 9 April 1969 (with Yes guitarist Peter Banks among the audience). Their big breakthrough came on 5 July 1969 by playing as a support act at the Rolling Stones' free concert in Hyde Park, London before an estimated 500,000 people. The debut album, In the Court of the Crimson King, was released in October 1969 on Island Records. Fripp would later describe it as having been "an instant smash" and "New York's acid album of 1970" (notwithstanding Fripp and Giles' assertion that the band never used psychedelic drugs). Who guitarist and composer Pete Townshend called the album "an uncanny masterpiece." The album contains Sinfield's gothic lyrics and its sound was described as having "dark and doom-laden visions". Its opening track "21st Century Schizoid Man" was described as "proto-metal" and the song's lyrics criticise the military involvement of the United States in Southeast Asia. In contrast to the blues-based hard rock of the contemporary British and American scenes, King Crimson presented a more Europeanised approach that blended antiquity and modernity. The band's music drew on a wide range of influences provided by all five group members. These elements included classical music, the psychedelic rock spearheaded by Jimi Hendrix, folk, jazz, military music (partially inspired by McDonald's stint as an army musician) and free improvisation.

After playing shows across England, the band toured the US with various pop and rock acts. Their first show was at Goddard College in Plainfield, Vermont. While the band found success and critical acclaim, creative tensions were already developing. Giles and McDonald, still striving to cope with King Crimson's rapid success and the realities of touring life, became uneasy with their musical direction. Although he was neither the dominant composer nor the frontman, Fripp was very much the group's driving force and spokesman, leading them into progressively darker and more intense musical areas. McDonald and Giles, now favouring a lighter and more nuanced romantic style, became increasingly uncomfortable with their position and resigned after the conclusion of the US tour in January 1970. To keep the band together, Fripp offered to resign himself, but McDonald declared that King Crimson was "more (him) than them" and that he and Giles should therefore be the ones to leave. McDonald later said he "was probably not emotionally mature enough to handle it" and made a "rash decision to leave without consulting anyone". The original line-up played their last show at the Fillmore West in San Francisco on 16 December 1969, a little over one year after forming. Live recordings of the band from 1969 were released in 1997 on Epitaph and in 2010 on the In the Court of the Crimson King (1969) box set.

1970–1971: In the Wake of Poseidon and Lizard
King Crimson spent 1970 in a state of flux with various line-up changes, thwarted tour plans, and difficulties in finding a satisfactory musical direction while Fripp was learning and developing as a songwriter during the writing process of the next three albums. As well as guitar, Fripp took on keyboard duties, while Sinfield expanded his creative role to operating synthesizers.

Following McDonald and Giles' departure, Lake, unsure of the band's future without them, began discussions with Keith Emerson of the Nice about possibly forming a new band together. With Fripp and Sinfield planning for recording the second King Crimson album, and Lake's position uncertain, the band's management booked Elton John to sing the material as a session musician, but Fripp decided against this idea after listening to his Empty Sky album. Lake agreed to stay with the band until Emerson had completed remaining commitments with the Nice, at which point he left to form Emerson, Lake and Palmer. On the resulting In the Wake of Poseidon album, Lake provided all the lead vocals except on "Cadence and Cascade", as he left before he was able to complete this track. Fripp's old school friend Gordon Haskell was brought in to provide the vocal on the song. The sessions also included Michael and Peter Giles on drums and bass respectively, saxophonist Mel Collins (formerly of the band Circus) and jazz pianist Keith Tippett. Upon its release in May 1970, In the Wake of Poseidon reached No. 4 in the UK and No. 31 in the US. It received some criticism from those who thought it sounded too similar to their first album. With no set band to perform the new material, Fripp and Sinfield kept Mel Collins on board, with Gordon Haskell joining as lead vocalist and bassist, and Andy McCulloch joining as drummer. In addition to saxophone, Collins would also act as occasional keyboard player and backing vocalist.

Fripp and Sinfield wrote the third album, Lizard, themselves – with Haskell, Collins and McCulloch having no say in the direction of the material. In addition to the core band, several session musicians contributed to the Lizard recording, including the returning Keith Tippett, who was offered full band membership but preferred to remain an occasional guest musician, and two members of Tippett's band, Mark Charig on cornet, and Nick Evans on trombone. Robin Miller (on oboe and cor anglais) also appeared, while Jon Anderson of Yes was brought in to sing a section of the album's title track, "Prince Rupert Awakes", which Fripp and Sinfield considered to be outside Haskell's natural range and style. Lizard featured stronger jazz and chamber-classical influences than previous albums. The album contains Sinfield's "phantasmagorical" lyrics, including "Happy Family" (an allegory of the break-up of the Beatles), and the title track, a suite which took up the entire second side, describing a medieval/mythological battle and its outcome.

Released in December 1970, Lizard reached No. 29 in the UK and No. 113 in the US. Described retrospectively as an "outlier", the album had been made by a group in disagreement over method and taste. The more rhythm-and-blues-oriented Haskell and McCulloch both found the music difficult to relate to, and tedious and confusing to record. Collins disliked how his parts were composed, while both Fripp and Haskell detested Sinfield's lyrics. This lineup of the band did not survive much longer than the Lizard recording sessions. Haskell quit the band acrimoniously during initial tour rehearsals after refusing to sing live with distortion and electronic effects on his voice, and McCulloch departed soon after. With Sinfield not being a musician and Fripp having seemingly given up on the band, Collins was left to search for new members.

1971–1972: Islands
After a search for a drummer to replace McCulloch, Ian Wallace was secured. Fripp was re-energised by the addition of a new member, and he joined Collins and Wallace to audition singers and bassists. Vocalists who tried out included Bryan Ferry of Roxy Music and even one of the band's managers, John Gaydon. The position eventually went to Raymond "Boz" Burrell. John Wetton was invited to join on bass, but declined in order to join Family instead. Rick Kemp (later of Steeleye Span) rehearsed with the band, but declined the final offer to formally join. Fripp decided to teach Boz to play bass rather than continue the labored auditions. Though he had not played bass before, Burrell had played enough acoustic guitar to assist him in learning the instrument quickly. Wallace was able to further instruct Burrell in functioning on the instrument in a rhythm section. With a line-up now complete, King Crimson began touring in May 1971, the first time they had played live since the original line-up's last show on 16 December 1969. The concerts were well received, but the musical differences between Fripp and the rest of the group, and the somewhat wilder lifestyles of Collins, Wallace and Burrell, alienated the drug-free Fripp, who began to withdraw socially from his bandmates, creating further tension.

In 1971, the new King Crimson formation recorded Islands. Sinfield, who favoured a softer approach, took lyrical inspiration from Homer's Odyssey, musical inspiration from jazz players like Miles Davis and Ahmad Jamal, and a sun-drenched trip to Ibiza and Formentera. Islands featured the instrumental "Sailor's Tale", with a droning Mellotron and Fripp's banjo-inspired guitar solo; the raunchy, blues-inspired "Ladies of the Road", which featured Wallace and Collins on backing vocals; and "Song of the Gulls", which was developed from an earlier Fripp instrumental ("Suite No. 1" from Giles, Giles & Fripp's 1968 album ), and would be the only time the band would utilize an orchestra. Burrell disliked Sinfield's lyrics and one of the band members allegedly called Islands as "an airy-fairy piece of shit".

Released in December 1971, Islands charted at No. 30 in the UK and No. 76 in the US. Following a tour of the United States in December 1971, Fripp informed Sinfield that he could no longer work with him, and asked him to leave the band. In January 1972, the remaining band broke up acrimoniously in rehearsals, owing partially to Fripp's refusal to play a composition by Collins. He later cited this as "quality control", with the idea that King Crimson would perform the "right" kind of music.

In order to fulfil touring contracts in the United States in 1972, King Crimson reformed with the intention of disbanding immediately after the tour. Recordings from various North American dates between January and February 1972 were released as Earthbound in June of that year. The album was noted for its playing style that occasionally veered towards funk, and Burrell's scat singing on the improvised pieces, but was criticised for its sub-par sound quality. Further, better-quality, live recordings from this era would be released in 2002 as Ladies of the Road and in 2017 on the Sailors' Tales (1970–1972) box set. By this time, the musical rift between Fripp and the rest of the band had grown very wide. Wallace, Burrell and Collins favoured improvised blues and funk. Fripp would later describe the 1971–1972 lineup as more of a jam band than an "improvising" band, an opinion with which Wallace disagreed. Personal relations actually improved during the tour to the point where most of the band decided to continue on, however Fripp opted to part company with the other three, restructuring King Crimson with new musicians, as he felt the other members wouldn't be fully engaged in the musical direction he had in mind.

1972–1975: Larks' Tongues in Aspic, Starless and Bible Black, Red and hiatus
The next incarnation of King Crimson was radically different from the previous configurations. Fripp's four new recruits were free-improvising percussionist Jamie Muir, drummer Bill Bruford, who left Yes at a commercial peak in their career in favour of the "darker" Crimson, bassist and vocalist John Wetton (who left Family), and violinist, keyboardist and flautist David Cross, whom Fripp had met when he was invited to a rehearsal of Waves, a band Cross was working in. Most of the musical compositions were collaborations between Fripp and Wetton, who each composed segments independently and fitted together those which they found compatible. With Sinfield gone, the band recruited Wetton's friend Richard Palmer-James (from the original Supertramp) as their new lyricist. Unlike Sinfield, Palmer-James was not an official member of King Crimson, playing no part in artistic decisions, visual ideas, or sonic directions; his sole contributions to the group were his lyrics, sent via mail from his home in Germany. Following a period of rehearsals, King Crimson resumed touring on 13 October 1972 at the Zoom Club in Frankfurt, with the band's penchant for improvisation (and Muir's startling stage presence) gaining them renewed press attention.

In January and February 1973, King Crimson recorded Larks' Tongues in Aspic in London which was released that March. The band's new sound was exemplified by the album's two-part title track – a significant change from what King Crimson had done before, the piece emphasised the sharp instrumental interplay of the band, and drew influence from modern classical music, noisy free improv, and even heavy metal riffing. The record displayed Muir's unusual approach to percussion, which included a self-modified drum kit, assorted toys, a bullroarer, mbira, gongs, balloons, thunder sheet and chains. On stage, Muir also employed unpredictable, manic movements, bizarre clothing, and fake blood capsules (occasionally spit or applied to the head), becoming the sole example of such theatrical stage activity in the band's long history. The album reached No. 20 in the UK and No. 61 in the US. After a period of further touring, Muir departed in 1973, quitting the music industry altogether. Muir told King Crimson's management that he had decided a musician's life was not for him, and he had chosen to join a Scottish Buddhist monastery. He offered to serve a period of notice which the management declined. Instead of reiterating Muir's decision, the management informed the band and the public that Muir had sustained an onstage injury caused by a gong landing on his foot. With Muir gone, the remaining members reconvened in January 1974 to produce Starless and Bible Black, released in March 1974, which earned them a positive Rolling Stone review. Though most of the album was recorded live during the band's late 1973 tour, the recordings were carefully edited and overdubbed to sound like a studio record, with "The Great Deceiver", "Lament" and the second half of "The Night Watch" the only tracks recorded entirely in the studio. The album reached No. 28 in the UK and No. 64 in the US. Following the album's release, the band began to divide once more, this time over performance. Musically, Fripp found himself positioned between Bruford and Wetton, who played with such force and increasing volume that Fripp once compared them to "a flying brick wall", and Cross, whose amplified acoustic violin was consistently being drowned out by the rhythm section, leading him to concentrate more on Mellotron and an overdriven electric piano. An increasingly frustrated Cross began to withdraw both musically and personally, with the result being that he was voted out of the group following the band's 1974 tour of Europe and America.

In July 1974, Fripp, Bruford, and Wetton began recording Red. Before recording began, Fripp, now increasingly disillusioned with the music industry, turned his attention to the works of English mystic J.G. Bennett and had a spiritual experience in which "the top of my head blew off". Most of the album had been developed during live improvisations before Fripp retreated into himself and "withdrew his opinion", leaving Bruford and Wetton to direct the recording sessions. The album contains one live track, "Providence", recorded on 30 June 1974 with Cross playing violin. Several guest musicians (including former members Ian McDonald and Mel Collins) contributed to the album. Released on 6 October 1974, Red went to No. 45 in the UK and No. 66 in the US. AllMusic called it "an impressive achievement" for a group about to disband, with "intensely dynamic" musical chemistry between the band members.

Two months before the release of Red, King Crimson's future looked bright (with talks regarding founder member Ian McDonald rejoining the group). However, Fripp wished not to tour as he felt increasingly disenchanted by the group and the music industry. He also felt the world was going to drastically change by 1981 and that he had to prepare for it. Despite a band meeting while touring the US in which Fripp expressed a desire to end the band, the group did not formally disband until 25 September 1974 and later Fripp announced that King Crimson had "ceased to exist" and was "completely over for ever and ever". It was later revealed that Fripp had attempted to replace himself with McDonald and Steve Hackett of Genesis, but this idea was rejected by the managers. Following the band's disbanding, the live album USA was released in May 1975, formed of recordings from their 1974 North American tour. It received some positive reviews, including "a must" for fans of the band and "insanity you're better off having". Issues with the tapes rendered some of Cross' playing inaudible, so Eddie Jobson of Roxy Music was hired to perform violin and keyboard overdubs in a studio; further edits were also made to allow the music to fit on a single LP. More live recordings from the 1972–1974 era would be issued as The Night Watch in 1997, and as part of the box sets The Great Deceiver (1992), Larks' Tongues in Aspic (1972–1973) (2012), The Road to Red (1974), and Starless (1973–1974) (both 2014). Between 1975 and 1981, King Crimson were completely inactive.

1981–1984: Discipline, Beat, Three of a Perfect Pair and second hiatus
In the late autumn of 1980, having spent several years on spiritual pursuits and then gradually returning to music (playing guitar for David Bowie, Peter Gabriel and Daryl Hall, pursuing an experimental solo career, leading instrumental new wave band The League of Gentlemen), Fripp decided to form a new "first division" rock group, but had no intentions of it being King Crimson. Having recruited Bill Bruford as drummer, Fripp asked singer and guitarist Adrian Belew to join, the first time Fripp would actively seek collaboration with another guitarist in a band and therefore indicative of Fripp's desire to create something unlike any of his previous work. After touring with Talking Heads, Belew agreed to join and also become the band's lyricist. Bruford's suggestion of his bassist Jeff Berlin was rejected as Fripp thought his playing was "too busy", so auditions were held in New York: on the third day, Fripp left after roughly three auditions, only to return several hours later with Tony Levin (who got the job after playing a single chorus of "Red"). Fripp later confessed that, had he known that Levin (whom Fripp had played with in Peter Gabriel's group) was available and interested, he would have selected him without holding auditions. Fripp named the new quartet Discipline, and they went to England to rehearse and write new material. They made their live debut at Moles Club in Bath, Somerset on 30 April 1981, and completed a short tour supported by the Lounge Lizards. By October 1981, the band had opted to change their name to King Crimson.

In 1981, King Crimson recorded Discipline with producer Rhett Davies. The album displayed a very different version of the band, with newer influences including post-punk, new wave, funk, minimalism, pointillism, world music and African percussion. With a sound described in The New Rolling Stone Album Guide as having a "jaw-dropping technique" of "knottily rhythmic, harmonically demanding workouts". The title track "Discipline" was described as a postminimalist rock song. Fripp intended to create the sound of a "rock gamelan", with an interlocking rhythmic quality to the paired guitars that he found similar to Indonesian gamelan ensembles. Fripp concentrated on playing complex picked arpeggios, while Belew provided an arsenal of guitar sounds that "often mimic animal noises". In addition to bass guitar, Levin used the Chapman Stick, a ten-string two-handed tapping, hybrid guitar and bass instrument which he played in an "utterly original style". Bruford experimented with cymbal-less acoustic kits and a Simmons SDS-V electronic drum kit. The band's songs were shorter in comparison to previous King Crimson albums, and very much shaped by Belew's pop sensibilities and quirky approach to writing lyrics. Though the band's previous taste for improvisation was now tightly reined in, one instrumental ("The Sheltering Sky") emerged from group rehearsals; while the noisy, half-spoken/half-shouted "Indiscipline" was a partially written, part-improvised piece created in order to give Bruford a chance to escape from the strict rhythmic demands of the rest of the album. Released in September 1981, Discipline reached No. 41 in the UK and No. 45 in the US.

In June 1982, King Crimson followed Discipline with Beat, the first King Crimson album recorded with the same band line-up as the album preceding it. Beat is the only album where Fripp had no involvement in the original mixing; Davies and Belew undertook production duties. The album had a linked theme of the Beat Generation and its writings, reflected in song titles such as "Neal and Jack and Me" (inspired by Neal Cassady and Jack Kerouac), "Heartbeat" (inspired by Carolyn Cassady's "Heart Beat: My Life with Jack and Neal"), "The Howler" (inspired by Allen Ginsberg's "Howl") and "Waiting Man" (inspired by William Burroughs). The album contained themes of life on the road, existential angst and romanticism. While Beat was more accessible, it had the improvised "Requiem", which featured Frippertronics, a guitar technique invented by Brian Eno and Robert Fripp using a tape loop system.

Recording Beat was faced with tension with Belew suffering high stress levels over his duties as front man, lead singer, and principal songwriter. On one occasion, he clashed with Fripp and ordered him out of the studio. As Beat reached No. 39 in the UK and No. 52 in the US, King Crimson resumed touring. "Heartbeat" was released as a single which peaked at No. 57 on the Billboard Mainstream Rock chart. Around this time the band released the VHS The Noise: Live in Frejus, a document of a show played at the Arena, Frejus, France on 27 August 1982, co-headlining with Roxy Music (whose set from the same show was also released on VHS as The High Road). The VHS was later re-released as part of the Neal and Jack and Me DVD in 2004.

King Crimson's next album, Three of a Perfect Pair, was recorded in 1983 and released in March 1984. Having encountered difficulty in both writing and determining a direction for the album, the band chose to record and call the album's first half a "left side" – four of the band's poppier songs plus an instrumental – and the second half a "right side" – experimental work, improvisations that drew influence from industrial music, plus the third part of the "Larks' Tongues in Aspic" series of compositions. The stress during the writing process and the tension between the band members manifested in both lyrical content and music, and the result is a "nerve-racking" album. The 2001 remaster of the album included the "other side", a collection of remixes and improvisational out-takes plus Levin's humorous song, "The King Crimson Barbershop". Three of a Perfect Pair peaked at No. 30 in the UK and No. 58 in the US, with "Three of a Perfect Pair" and "Sleepless" being released as singles. A VHS document of the Three of a Perfect Pair tour, Three of a Perfect Pair: Live in Japan, was released later in 1984 (and later also included on the Neal and Jack and Me DVD). The last concert of the Three of a Perfect Pair tour, at the Spectrum in Montreal, Canada on 11 July 1984, was recorded and released in 1998 as Absent Lovers: Live in Montreal. Further live recordings of the 1980s band would be released in 2016 as part of the On (and off) The Road (1981–1984) box set. Despite their conflict, the musicians remained professional on stage.

Following the 1984 tour, Fripp dissolved King Crimson for the second time, exactly ten years after dissolving the previous group. Bruford and Belew expressed some frustration over this; Belew recalled the first he had heard of the split was when he read about it in a report in Musician magazine.

1994–1999: The Double Trio, Vrooom, THRAK and the ProjeKcts
In the summer of 1991, Belew met with Fripp in England to express an interest in reviving King Crimson. One year later, Fripp established his Discipline Global Mobile (DGM) record label with producer David Singleton. Subsequently, DGM would be the primary home for Fripp's work, with larger album releases distributed to bigger record companies (initially Virgin records), and smaller releases handled by DGM. This afforded Fripp and his associates greater creative freedom and more control over all aspects of their work. In late 1991, Fripp asked former Japan singer David Sylvian to join the new King Crimson band, but Sylvian declined the offer, though the two collaborated as Sylvian/Fripp. In June 1993, Fripp began to assemble a larger version of the band, joined by Belew and Levin from the 1980s quartet, Chapman Stick player Trey Gunn (a veteran of Fripp's Guitar Craft courses ) and drummer Jerry Marotta, with whom Fripp had played with Peter Gabriel. After Sylvian/Fripp's closing concerts at the Royal Albert Hall in December 1993, a tour that Marotta didn't participate in, Fripp decided to ask the tour's drummer Pat Mastelotto, formerly of Mr. Mister, to join instead of Marotta. Bruford wound up being the last of the 1980s group to return to the band. Fripp explained that he had a vision of a "Double Trio" with two drummers while driving along the Chalke Valley one afternoon in 1992. Bruford later said he lobbied Fripp last minute because he believed that Crimson was very much "his gig", and that Fripp had come up with a philosophical explanation for utilizing both Mastelotto and himself later. One of the conditions Fripp imposed upon Bruford if he were to return was to give up all creative control to Fripp.

Following rehearsals in Woodstock, New York, the group released the extended play Vrooom in October 1994. This revealed the new King Crimson sound, which featured the interlocking guitars of the 1980s mixed with the layered, heavier feel of the 1970s period. There was also a vague influence from the industrial music of that time. Many of the songs were written or finalised by Belew, and displayed stronger elements of 1960s pop than before; in particular, a Beatles influence. Bruford would refer to the band as sounding like "a dissonant Shadows on steroids". As with previous line-ups, new technology was utilised, including MIDI (extensively used as an effects filter by Belew and Gunn, and which Fripp used to replace Frippertronics with an upgraded digital version of itself called "Soundscapes") and the versatile Warr tap guitar with which Gunn replaced his Stick in 1995. King Crimson toured the album from 28 September 1994 in Buenos Aires, Argentina; portions of these concerts were released on the double live CD set B'Boom: Live in Argentina in 1995.

In October and December 1994, King Crimson recorded their eleventh studio album, THRAK. Formed mostly of revised versions of the tracks from Vrooom, plus new tracks, the album was described by Q magazine as having "jazz-scented rock structures, characterised by noisy, angular, exquisite guitar interplay" and an "athletic, ever-inventive rhythm section," while being in tune with the sound of alternative rock of the mid-1990s. Examples of the band's efforts to integrate their multiple elements could be heard on the accessible (but complex) songs "Dinosaur" and "Sex Sleep Eat Drink Dream", the more straightforward ballad "One Time", as well as "Radio I" and "Radio II"- a pair of Fripp's Soundscapes instrumentals.

King Crimson resumed touring in 1995 and into 1996; dates from October and November 1995 were recorded and released on the live album Thrakattak in May 1996, which is an hour of improvised music integrating sections from performances from the "THRAK" tour in the United States and Japan, mixed and arranged by Fripp's DGM partner, engineer David Singleton. A more conventional live recording from the period was later made available as the double CD release Vrooom Vrooom (2001), while a full 1995 concert was released on VHS in 1996 as Live in Japan and re-released on DVD in 1999 as Déjà Vrooom. The double trio would be further honored by the THRAK (1994–1997) box set in 2015.

Writing rehearsals began in May 1997 in Nashville, Tennessee. Fripp was dissatisfied with the quality of the new music being developed by the band; Longstanding friction and disagreements between himself and Bruford led to the latter deciding to leave King Crimson for good. The resulting bad atmosphere and the lack of workable material almost broke the band up altogether. Instead, the six members opted to work in four smaller groups (or "fraKctalisations", as Fripp called them) known as ProjeKcts. This enabled the group to continue developing ideas and searching for a new direction without the practical difficulty (and expense) of convening all six musicians at once. From 1997 to 1999, the first four ProjeKcts played live in the United States and the United Kingdom, and released recordings that showed a high degree of free improvisation, with influences ranging from jazz, industrial, techno and drum'n'bass. These have been collectively described by music critic J. D. Considine as "frequently astonishing" but lacking in melody. After Bruford had played four dates with Projekct One in December 1997, he left King Crimson to resume working with his own jazz group Earthworks.

1999–2003: The Double Duo, The Construkction of Light and The Power to Believe
In October 1999, King Crimson reconvened. Tony Levin was busy working as a session musician and decided to take a hiatus from the group, so the remaining members (Fripp, Belew, Gunn and Mastelotto) formed the "Double Duo" to write and record The Construkction of Light in Belew's basement studio and garage near Nashville. Fripp was inspired by Tool's album Undertow during the writing process of The Construkction of Light. Released in May 2000, the album reached No. 129 in the UK. Most of the pieces were metallic, harsh and industrial in sound. They featured a distinct electronic texture, a heavily processed electric drum sound from Mastelotto, Gunn taking over the bass role on Warr Guitar, and a different take on the interlocking guitar sound that the band had pioneered in the 1980s. With the exception of an industrial blues (sung by Belew through a voice changer under the pseudonym of "Hooter J. Johnson"), the songs were dense and complex. The album contains the fourth installment of "Larks' Tongues in Aspic". It received a negative reception for lacking new ideas. The band recorded an album of improvised instrumentals at the same time, and released them under the name ProjeKct X, on the CD Heaven and Earth.

King Crimson toured to support both albums, including double bill shows with Tool. The tour was documented on the live album Heavy ConstruKction in 2000 and the Heaven & Earth (1997–2008) box set in 2019. Led Zeppelin bassist John Paul Jones and his band supported Crimson on some live shows.

On 9 November 2001, King Crimson released a limited edition live extended play called Level Five, featuring three new pieces: "Dangerous Curves", "Level Five" and "Virtuous Circle", plus versions of "The Construkction of Light" and ProjeKct's "The Deception of the Thrush", followed by an unlisted track called "ProjeKct 12th and X" after one minute of silence. A second EP followed in October 2002, Happy with What You Have to Be Happy With. This featured eleven tracks (including a live version of "Larks' Tongues in Aspic, Part IV"). Half of the tracks were processed vocal snippets by Belew, and the songs themselves varied between Soundscapes, gamelan, heavy metal and blues.

The current King Crimson "Double Duo" line-up released their thirteenth album, The Power to Believe, in March 2003. Fripp described it as "the culmination of three years of Crimsonising". The album incorporated, reworked and retitled versions of "Deception of the Thrush" ("The Power to Believe III"); tracks from their previous two EPs; and an extract from a Fripp Soundscape with added instrumentation and vocals. The Power to Believe reached No. 162 in the UK and No. 150 in the US. King Crimson toured in 2003 to support the album; recordings from it were used for the live album EleKtrik: Live in Japan. 2003 also saw the release of the DVD Eyes Wide Open, a compilation of the band's shows Live at the Shepherds Bush Empire (London, 3 July 2000) and Live in Japan (Tokyo, 16 April 2003).

In November 2003, Gunn left the group to pursue solo projects and was replaced by the returning Tony Levin. The band reconvened in early 2004 for rehearsals, but nothing developed from these sessions. They went on another hiatus. At this point, Fripp was publicly reassessing his desire to work within the music industry, often citing the unsympathetic aspects of the life of a touring musician, such as "the illusion of intimacy with celebrities".

On 21 September 2006, former King Crimson member Boz Burrell died of a heart attack, followed by another former member, Ian Wallace, who died of esophageal cancer on 22 February 2007.

2008: 40th Anniversary tour and third hiatus


A new King Crimson formation was announced in 2007: Fripp, Belew, Levin, Mastelotto, and a new second drummer, Gavin Harrison. In August 2008, after a period of rehearsals, the five completed the band's 40th Anniversary Tour. The setlists featured no new material, drawing instead from the existing mid '70s era/Discipline-era/Double Trio/Double Duo repertoire. Additional shows were planned for 2009, but were cancelled due to scheduling clashes with Belew.

King Crimson began another hiatus after the 40th Anniversary Tour. Belew continued to lobby for reviving the band, and discussed it with Fripp several times in 2009 and 2010. Among Belew's suggestions was a temporary reunion of the 1980s line-up for a thirtieth anniversary tour: an idea declined by both Fripp and Bruford, the latter commenting "I would be highly unlikely to try to recreate the same thing, a mission I fear destined to failure." In December 2010, Fripp wrote that the King Crimson "switch" had been set to "off" since October 2008, citing several reasons for this decision.

In August 2012, Fripp announced his retirement from the music industry, leaving the future of King Crimson uncertain.

2014–2021: The Seven-Headed Beast and Three Over Five line-ups
Prior to Fripp's retirement announcement, a band called Jakszyk, Fripp and Collins (and subtitled "A King Crimson ProjeKct") had released an album called A Scarcity of Miracles in 2011. The band featured guitarist and singer Jakko Jakszyk (who'd previously performed King Crimson material with 21st Century Schizoid Band), Fripp and former Crimson saxophonist Mel Collins as the main players/composers, with Tony Levin playing bass and Gavin Harrison playing drums. At one point, Fripp referred to the band as "P7" (ProjeKct Seven). Unusually for a ProjeKct, it was based around "finely crafted" and "mid-paced" original songs derived from improvised sessions.

In September 2013, Fripp announced King Crimson's return to activity with a "very different reformation to what has gone before: seven players, four English and three American, with three drummers". He cited several reasons to make a comeback, varying from the practical to the whimsical: "I was becoming too happy. Time for a pointed stick." The new line-up drew from both the previous lineup (retaining Fripp, Levin, Harrison and Mastelotto) and the Scarcity of Miracles project (Jakszyk and Collins), with Guitar Craft alumnus and former R.E.M./Ministry drummer Bill Rieflin as the seventh member. Adrian Belew was not asked to take part, thus ending his 32-year tenure in King Crimson: Jakszyk took his place as singer and second guitarist. This version of the group took on the nickname of "the Seven-Headed Beast".

This drastically revamped King Crimson had no plans to record in the studio, focussing instead on playing "reconfigured" versions of past material in live concerts. For the most part, this approach would remain consistent for the remainder of the band's lifetime. In early 2014, and for the first time since 1974, the band's repertoire included songs from the run of albums between In The Court of the Crimson King and Larks' Tongues in Aspic as well as reviving song material from Red. No Adrian Belew-era songs were included in the setlist, although some instrumentals from the period were played (including items from THRAK and The Power to Believe). At the same time, two brand new songs mainly written by Fripp and Jakszyk ("Meltdown" and "Suitable Grounds for the Blues") were debuted at live concerts.

After rehearsing in England, King Crimson toured North America from 9 September to 6 October. Recordings from the Los Angeles dates were released as Live at the Orpheum: this included new King Crimson instrumental music in the shape of "Banshee Legs Bell Hassle" and "Walk On: Monk Morph Chamber Music".

Tours across Europe, Canada, and Japan followed in the later half of 2015. A live recording from the Canadian leg of the tour was released at the end of February 2016 as Live In Toronto, which included three more new Crimson instrumental pieces ("Threshold Soundscape", "Radical Action (To Unseat the Hold of Monkey Mind)" and "The Hell Hounds of Krim"). A European tour was planned for 2016. Following Rieflin's decision to take a break from music, drummer Jeremy Stacey of Noel Gallagher's High Flying Birds was called in place for dates from September.

Bottom L-R: Mastelotto, Stacey, Harrison.Top L-R: Collins, Levin, Rieflin, Jakszyk, Fripp.]] A further live album, Radical Action to Unseat the Hold of Monkey Mind, was released in September 2016, drawing from 2015 concert dates of Japan, Canada and France preceding Rieflin's departure and Stacey's arrival. Further documenting the band's shuffling and evolving live set, it included one new instrumental ("Devil Dogs of Tessellation Row") and demonstrated that King Crimson were now incorporating material from A Scarcity of Miracles (the title track, plus "The Light of Day") into the band's repertoire.

On 7 December 2016, founding King Crimson member Greg Lake died of cancer. Another former King Crimson member, John Wetton, died of colon cancer on 31 January 2017.

On 3 January 2017, Bill Rieflin returned to King Crimson. Since the band wished to retain Jeremy Stacey, Fripp called the new lineup the "Double Quartet Formation", referencing four drummers. Consequently, King Crimson became an octet, with Fripp rechristening the line-up the "Three Over Five" (or "Five Over Three") Formation. Later on, Rieflin shifted his group role and became King Crimson's first full-time keyboard player.

On 2 June 2017, King Crimson released a new live EP named "Heroes" (after the David Bowie song), as a tribute to both the artist and the album featuring the song in question, both of which featured distinctive Robert Fripp guitar contributions throughout. The video to the song won "Video of the Year" at the 2017 Progressive Music Awards. Shortly afterwards, King Crimson embarked on a United States tour beginning on 11 June and ending on 26 November. On 3 September, Robert Fripp said that his differences with Adrian Belew had been resolved and that there were "no current plans for (him) to come out with the current formation" but "the doors to the future are open." Belew confirmed this, adding "it means I may be back in the band in the future at some point."

On 14 October 2017, King Crimson released another contemporary live album, Live in Chicago, recorded on tour in June of the same year. As had been the case with its two predecessors, it included new music in the absence of a new studio album (in this case "Bellscape & Orchestral Werning", "The Errors" and "Interlude"). It also documented the return to the live set of material from the long-neglected 1970 album Lizard (in the form of the full "Lizard Suite" from the second side), as well as another live version of "'Heroes'" and a radically different version of the Belew-era song "Indiscipline".

On 13 October 2017, it was announced that Bill Rieflin would be unable to join the Three Over Five Formation on the 2017 Autumn tour in the U.S. He was temporarily replaced by Seattle-based Crafty Guitarist Chris Gibson. During 2018, King Crimson performed the extensive 33-date Uncertain Times tour through the UK and Europe between 13 June and 16 November.

Although the band continued their "no new studio album" policy, April 2018 saw the full release of another live album, Live in Vienna, compiling concert recordings from Vienna in 2016 and from Tokyo in 2015. Although the only new band piece on this occasion was the brief drum trio "Fairy Dust of the Drumsons", the set also included three pieces drawn from improvised Fripp/Collins/Levin introduction music and merged with Fripp soundscape music: these pieces were arranged and realised by David Singleton, reflecting similar work he'd performed for  THRaKaTTaK twenty years earlier. On 20 October 2018, a further live album was released, Meltdown: Live in Mexico City, recorded during dates in July 2017: additions to the setlist on this album included another new drum piece ("CatalytiKc No. 9"), the readmission of another Belew-era song ("Neurotica), "Breathless" (from Fripp's 1979 solo album Exposure), a group jam and assorted solo member "cadenzas".

On 6 April 2019, it was announced at a press conference that Rieflin would take another break from King Crimson to attend to family matters, his place on keyboards for the 2019 50th anniversary tour taken by Theo Travis, better known as a saxophonist, Soft Machine member and occasional duo collaborator with Robert Fripp. Although Travis joined the band for rehearsals, Fripp said on 2 May that the band had decided that it was no longer possible to have other musicians deputising for Rieflin and for this reason were "proceed(ing) as a Seven-Headed Beast" without Travis. Rieflin's parts were divided among other band members, with Fripp, Stacey, Jakszyk and Collins adding keyboards to their on-stage rigs, and Levin once again using the synthesizer he used during the '80s tours. Soon after on 11 June, King Crimson's entire discography was made available to stream online on all the major streaming platforms, as part of the band's 50th anniversary celebration.

On 24 March 2020, Bill Rieflin died of cancer. In the same year, former member Gordon Haskell died of lung cancer on 15 October.

King Crimson toured North America and then Japan in 2021. Recordings from dates on the American leg of the tour were released as the "official bootleg" live album Music Is Our Friend: Live in Washington and Albany, featuring music from across the band's lifetime plus two new Tony Levin cadenzas.

2022: In the Court of the Crimson King documentary and end of band activity
Following the 2021 tour dates, King Crimson ceased activity, although without expressly announcing a breakup. Reasons cited were practical ones involving the old age of several of the members plus the rising cost of services during the pandemic, with no band intentions for any more tours.

In August 2021, Jakszyk referred to the existence of "about forty to fifty minutes' worth of new (King Crimson) stuff, a number of songs I've co-written with Robert and some instrumental things he's written. During the lockdown Gavin suggested, 'Why don't we record these things so we've at least got studio recordings of this material?' That doesn't mean we're going to make a new album or it's ever gonna come out, but we have started this process." Versions of two Fripp/Jakszyk songs originally intended for King Crimson ("Uncertain Times" and "Separation") had already emerged on Jakszyk's 2020 solo album Secrets and Lies, with participation from Fripp, Harrison, Levin and Collins.

On 9 February 2022, founding King Crimson member Ian McDonald died of cancer.

In March 2022, the documentary film In the Court of the Crimson King was premiered at the 2022 SXSW Film Festival. Directed by Toby Amies and filmed between 2019 and 2021, it covered live and backstage activity by the then-current band but also featured a historical overview plus contributions from Crimson alumni Ian McDonald, Michael Giles, Bill Bruford, Adrian Belew and Trey Gunn (as well as prolonged interview footage with the late Bill Rieflin). Amies described the film's development as follows: “What began as a traditional documentary about the legendary band King Crimson as it turned fifty, mutated into an exploration of time, death, family, and the transcendent power of music to change lives; but with jokes.”

As of 2022, with the exception of archive/curatorial matters, King Crimson has ceased activity altogether, with no plans for the future. Levin said in a late 2022 interview that, "the sense I got from Robert [Fripp] was that it's over. Maybe King Crimson will speak to him in the future in some way, and will revive its head with who-knows-what line up?"

At a post-screening Q&A session for In the Court of the Crimson King, Fripp referred to the seven-member 2021 lineup of King Crimson as "the final incarnation" of the band. Asked if there could ever be a line-up that did not include him, he disagreed, stating "I see the whole. I see the music. I see the musicians. I see the audience and I see the music industry [...] and you have to engage with all of that to have the overview. So that's the quick answer."

Musical style
King Crimson have been described musically as progressive rock, art rock, and post-progressive, with their earlier works being described as proto-prog. Their music was initially grounded in the rock of the 1960s, especially the acid rock and psychedelic rock movements. The band played Donovan's "Get Thy Bearings" in concert, and were known to play the Beatles' "Lucy in the Sky with Diamonds" in their rehearsals. However, for their own compositions, King Crimson (unlike the rock bands that had come before them) largely stripped away the blues-based foundations of rock music and replaced them with influences derived from classical composers. The first incarnation of King Crimson played the Mars section of Gustav Holst's suite The Planets live and later the band used Mars as a foundation for the song "Devil's Triangle". As a result of this influence, In the Court of the Crimson King is frequently viewed as the nominal starting point of the progressive rock movements. King Crimson also initially displayed strong jazz influences, most obviously on its signature track "21st Century Schizoid Man". The band also drew on English folk music for compositions such as "Moonchild" and "I Talk to the Wind." In the 1972 lineup, Fripp's intention was to combine the music of Jimi Hendrix, Igor Stravinsky and Béla Bartók.

The 1981 reunion of the band brought in even more elements, displaying the influence of funk, post-punk, new wave, gamelan music and late 20th century classical composers such as Philip Glass, Steve Reich, and Terry Riley. For its 1994 reunion, King Crimson reassessed both the mid-1970s and 1980s approaches in the light of new technology, intervening music forms such as electronica, drum'n'bass and techno; and further developments in industrial music, as well as expanding the band's ambient textural content via Fripp's Soundscapes looping approach.

The 2013 version of the band returned, for the most part, to the band's 1960s and 1970s influences and repertoire but addressed them via current technology and rearrangements suited to a larger ensemble of more experienced musicians, while also incorporating the New Standard Tuning used by Fripp since 1984.

Compositional approaches
Several King Crimson compositional approaches remained constant throughout the band's lifetime. These included:


 * The use of a gradually building rhythmic motif. These include "The Devil's Triangle" (an adaptation and variation on the Gustav Holst piece Mars played by the original King Crimson, based on a complex pulse in time over which a skirling melody is played on a Mellotron), 1973's "The Talking Drum" (from Larks' Tongues in Aspic), 1984's "Industry" (from Three of a Perfect Pair) and 2003's "Dangerous Curves" (from The Power to Believe).
 * An instrumental piece (often embedded as a break in a song) in which the band played an ensemble passage of considerable rhythmic and polyrhythmic complexity. An early example is the band's initial signature tune "21st Century Schizoid Man", but the "Larks' Tongues in Aspic" series of compositions (as well as pieces of similar intent such as "THRAK" and "Level Five") went deeper into polyrhythmic complexity, delving into rhythms that wander into and out of general synchronisation with each other, but with all 'finishing' together through polyrhythmic synchronisation. These polyrhythms were particularly abundant in the band's 1980s work, which contained gamelan-like rhythmic layers and continual overlaid staccato patterns in counterpoint.
 * The composition of difficult solo passages for individual instruments, such as the guitar break on "Fracture" on Starless and Bible Black.
 * The juxtaposition of ornate tunes and ballads with unusual, often dissonant noises (such as "Cirkus" from Lizard, "Ladies of the Road" from Islands and "Eyes Wide Open" from The Power to Believe).
 * The use of improvisation.
 * Ascending note structure (e.g. "Facts of Life" and "THRAK").

Improvisation
King Crimson incorporated improvisation into their performances and studio recordings from the beginning, some of which was embedded into pieces such as "Moonchild", "Providence", "Requiem" and "No Warning", including passages of restrained silence, as with Bill Bruford's contribution to the improvised "Trio". Rather than using the standard jazz or rock "jamming" format for improvisation (in which one soloist at a time takes centre stage while the rest of the band lies back and plays along with established rhythm and chord changes), King Crimson improvisation consisted of musicians collectively making creative decisions and contributions as the music is being played. Individual soloing was largely eschewed; each musician was to listen to each other and to the group sound, to be able to react creatively within the group dynamic. Fripp has used the metaphor of "magic" to describe this process, in particular when the method works particularly well.

Similarly, King Crimson's improvised music was varied in sound and the band has been able to release several box sets and albums consisting mostly or entirely of improvised music, such as the THRaKaTTaK album, and the band's series of ProjeKcts. Occasionally, particular improvised pieces were recalled and reworked in different forms at different shows, becoming more and more refined and eventually appearing on official studio releases.

Influence and legacy
King Crimson have been influential both on the early 1970s progressive rock movement and numerous contemporary artists. Genesis and Yes were directly influenced by the band's usage of the mellotron, and many King Crimson band members were involved in other notable bands: Bruford in Yes; Lake in Emerson, Lake & Palmer; McDonald in Foreigner; Burrell in Bad Company, and Wetton in U.K. and Asia. Canadian rock band Rush's drummer Neil Peart credited the adventurous and innovative style of Michael Giles as an influence on his own approach to percussion.

King Crimson's influence extends to many bands from diverse genres, especially of the 1990s and 2000s. Kurt Cobain, the frontman of the grunge band Nirvana, had stated that the album Red had a major influence on the sound of their final studio album In Utero. Tool are known to be heavily influenced by King Crimson, with vocalist Maynard James Keenan joking on a tour with them: "Now you know who we ripped off. Just don't tell anyone, especially the members of King Crimson." Modern progressive, experimental, psychedelic and indie rock bands have cited them as an influence as well, including the Mars Volta, Primus,  Mystery Jets,  Fanfarlo, Phish, and Anekdoten, who first practiced together playing King Crimson songs. Steven Wilson, the leader of Porcupine Tree, was responsible for remixing King Crimson's back catalogue in surround sound and said that the process had an enormous influence on his solo albums, and his band was influenced by King Crimson. In November 2012 the Flaming Lips in collaboration with Stardeath and White Dwarfs released a track-by-track reinterpretation of In the Court of the Crimson King entitled Playing Hide and Seek with the Ghosts of Dawn. Colin Newman, of Wire, said he saw King Crimson perform many times, and that they influenced him deeply. The seminal hardcore punk group Black Flag acknowledge Wetton-era King Crimson as an influence on their experimental period in the mid-1980s. Melvin Gibbs said that the Rollins Band was influenced most by King Crimson, using similar chords. Bad Religion cites the lyrics of "21st Century Schizoid Man" on their single "21st Century (Digital Boy)" and the name of their record label, Epitaph (founded by their guitarist Brett Gurewitz), comes from the song of the same name on Crimson's debut album. Living Colour guitarist Vernon Reid considered Robert Fripp as one of his guitar influences.

King Crimson have frequently been cited as pioneers of progressive metal and as an influence on bands of this genre, including Opeth, Mastodon,  Between the Buried and Me,  Leprous,  Haken, the Ocean, Caligula's Horse, Last Chance to Reason, and Indukti. Members of metal bands Mudvayne, Voivod, Enslaved, Yob, Pyrrhon, and Pallbearer have cited King Crimson as an influence. Heavy experimental and avant-garde acts like the Dillinger Escape Plan, Neurosis, Zeni Geva, Ancestors, and Oranssi Pazuzu all cite King Crimson's influence.

Other artists affected by King Crimson include video game composer Nobuo Uematsu, noise music artist Masami Akita of Merzbow, jazz guitarist Dennis Rea of Land, folktronica exponent Juana Molina, hip hop producer RJD2, hip hop and soul composer Adrian Younge, film director Hal Hartley, and folk-pop singer Ian Kelly.

Related legacy/cover bands featuring former King Crimson members
Since the early 2000s, several bands containing former, recent or current King Crimson members have toured and recorded, performing King Crimson music.

Active between 2002 and 2005, the 21st Century Schizoid Band reunited several former King Crimson members who had played on the band's first four albums. The band featured Ian McDonald, Mel Collins, Peter Giles and Michael Giles (the latter subsequently replaced by Ian Wallace), and was fronted by Jakko Jakszyk, a decade prior to his own recruitment into King Crimson. The band engaged in several tours, played material from King Crimson's '60s and '70s catalogue, and recorded several live albums. The band disbanded upon Wallace's death in 2007.

Since 2007, Tony Levin has led the trio Stick Men, which also features Pat Mastelotto. The band was initially completed by Chapman Stick player Michael Bernier, replaced in 2010 by touch guitarist and former Fripp student Markus Reuter. This band includes (and reinterprets) King Crimson compositions in their live sets. Reuter and Mastelotto also play together as a duo (previously called "Tuner"), within which they have been known to rework the mid-1980s King Crimson instrumental "Industry" live.

Between 2011 and 2014, Stick Men and Adrian Belew's Power Trio band (Belew plus drummer Tobias Ralph and bass player Julie Slick) joined forces to play and tour as The Crimson ProjeKCt, covering the music made during the '80s and '90s. Following the return of King Crimson in 2014, the Crimson ProjeKct name has been formally abandoned, but the Stick Men and the Power Trio have still performed together from time to time, usually under names like "Belew, Levin, Mastelotto and friends".

During his solo career, including performances with the Power Trio, Adrian Belew has performed various versions of King Crimson songs.

In March 2024, a new group performing the 1980's King Crimson repertoire was announced featuring former members Adrian Belew and Tony Levin along with guitarist Steve Vai and drummer Danny Carey. The band is named "Beat" after the 1982 album of the same name.
