Dream Theater

Dream Theater is an American progressive metal band formed in 1985 in Boston, Massachusetts. The band comprises John Petrucci (guitar), John Myung (bass), Mike Portnoy (drums), James LaBrie (vocals) and Jordan Rudess (keyboards).

Dream Theater was formed under the name Majesty by Petrucci, Myung and Portnoy — all natives of Long Island, New York — while they attended Berklee College of Music. They dropped out to concentrate on the band. Petrucci and Myung have been the only two constant members. Portnoy had remained until 2010, when he was replaced by Mike Mangini after deciding to leave to pursue other musical projects before rejoining Dream Theater in October 2023. After a brief stint with Chris Collins, followed by Charlie Dominici (who was dismissed from Dream Theater not long after the release of their first album), LaBrie was hired as the band's singer in 1991. Dream Theater's first keyboardist, Kevin Moore, left the band after three albums and was replaced by Derek Sherinian in 1995 after a period of touring. The band recorded one album with Sherinian, who was replaced by current keyboardist Jordan Rudess in 1999.

Dream Theater has released fifteen studio albums. The band's highest-selling release is their second album Images and Words (1992), which reached No. 61 on the Billboard 200 chart. The albums Awake (1994) and Six Degrees of Inner Turbulence (2002) also entered the charts at No. 32 and No. 46 respectively, and each received critical acclaim. Their fifth album, Metropolis Pt. 2: Scenes from a Memory (1999), was ranked number 95 on the October 2006 issue of Guitar World magazine's list of the greatest 100 guitar albums of all time. It was also ranked as the 15th Greatest Concept Album in March 2003 by Classic Rock magazine.

As of 2018, Dream Theater has sold over 12 million records worldwide and has received three Grammy Award nominations (including one win in 2022). Along with Queensrÿche and Fates Warning, the band has been referred to as one of the "big three" of the progressive metal genre, responsible for its development and popularization.

Formation (1985–1987)
Dream Theater (then-Majesty) was formed in Massachusetts in 1985 when guitarist John Petrucci, bassist John Myung, and drummer Mike Portnoy decided to form a band while attending Berklee College of Music in Boston. Petrucci and Myung were childhood friends from Kings Park, New York, and met Portnoy of Long Beach, New York while at Berklee. The trio started by covering Rush and Iron Maiden songs in the rehearsal rooms at Berklee.

Myung, Petrucci, and Portnoy joined on the name Majesty for their newly formed group. According to The Score So Far... documentary, they were waiting in line for tickets to a Rush concert at the Berklee Performance Center while listening to the band on a boom box. Portnoy commented that the ending of the song "Bastille Day" (from the album Caress of Steel) sounded "majestic". It was then decided that Majesty would be the band's name.

The trio then set out to fill the remaining positions in the group. Petrucci asked his high school bandmate Kevin Moore to play the keyboard. After he accepted the position, another friend from home, Chris Collins, was recruited as lead vocalist after band members heard him sing a cover of "Queen of the Reich" by Queensrÿche. During this time, Portnoy, Petrucci, and Myung's hectic schedules forced them to abandon their studies to concentrate on their music, as they did not feel they could learn more in college. Moore also left his college, SUNY Fredonia, to concentrate on the band.

The beginning months of 1986 were filled with various concert dates in and around the New York City area. During this time, the band recorded a collection of demos, titled The Majesty Demos. The initial run of 1,000 sold out within six months, and dubbed copies of the cassette became popular within the progressive metal scene. The Majesty Demos are still available in their original tape format today, despite being released officially on CD, through Mike Portnoy's YtseJam Records (and on InsideOut in 2022, after YtseJam Records was shut down).

In November 1986, after a few months of writing and performing together, Chris Collins was fired. After a year of trying to find a replacement, Charlie Dominici, who was far older and more experienced than anyone else in the band, successfully auditioned for the group. With the stability that Dominici's appointment brought to Majesty, they began to increase the number of shows played in the New York City area, gaining a considerable amount of exposure.

Shortly after hiring Dominici, a Las Vegas group also named Majesty threatened legal action for intellectual property infringement related to the use of their name, so the band was forced to come up with a new one. Various possibilities were proposed and tested, among them Glasser, Magus, and M1, which were all rejected, though the band did go as Glasser for about a week, with poor reactions from fans. Eventually, Portnoy's father suggested the name Dream Theater, the name of a small theater in Monterey, California, and the name stuck.

When Dream and Day Unite (1988–1990)
With their new name and band stability, Dream Theater concentrated on writing more material while playing more concerts in New York and in neighboring states. This eventually attracted the attention of Mechanic Records, a division of MCA. Dream Theater signed their first record contract with Mechanic on June 23, 1988 and set out to record their debut album. The band recorded the album at Kajem Victory Studios in Gladwyne, Pennsylvania. Recording the basic tracks took about ten days, and the entire album was completed in about three weeks.

When Dream and Day Unite was released in 1989 to far less fanfare than the band had anticipated. Mechanic ended up breaking the majority of the financial promises they had made to Dream Theater prior to signing their contract, so the band was restricted to playing around New York City. The promotional tour for the album consisted of just five concerts, all of which were relatively local. Their first show was at Sundance in Bay Shore, New York opening for the classic rock power trio Zebra.

After the fourth show, Charlie Dominici was let go because the band was starting to feel the limitations of his voice based upon the vocal style they wanted. The band was looking for a singer with a style more like Bruce Dickinson or Geoff Tate, and Dominici's stage presence was not what they wanted for a frontman. Shortly after, however, the band Marillion asked Dream Theater to open for them at a gig at the Ritz in New York, so Dominici was given the opportunity to perform one last time. It would be another two years before Dream Theater had a replacement vocalist.

Addition of James LaBrie and Images and Words (1991–1993)
Following Dominici's departure, Dream Theater fought successfully to be released from their contract with Mechanic and set about auditioning singers and writing material for their next album. In their search for a new singer, they auditioned over 200 people, among them former Fates Warning front man John Arch. Arch ultimately decided that his personal commitments were more important and he opted not to join the band. On June 9, 1990, at a gig at Sundance in Bay Shore, New York, Dream Theater introduced Steve Stone as their new singer after playing half the set as an instrumental band. Stone had successfully recorded demos with Dream Theater, but he was fired following a single, ill-fated live performance. According to Mike Portnoy, Stone moved around the stage in a rather odd manner, seemingly doing a bad impression of Bruce Dickinson. Additionally, he shouted "Scream for me Long Beach!" several times throughout the show (Dickinson can be heard saying this on Iron Maiden's live album Live After Death), although they were actually performing in Bay Shore. The audience was immediately turned off by the new singer. It was five months before Dream Theater played another show, this time all-instrumental (under the name YtseJam). Until 1991, the band remained focused in an attempt to hire another singer and writing additional music. It was during this period that they wrote the majority of what would become Images and Words (1992).

In January 1991, the band received a demo tape from Kevin James LaBrie, of glam metal band Winter Rose. The band had received the tape just before they were about to commit to another singer. The band was so impressed by his demo that he was flown from Canada to New York for an audition. LaBrie jammed on three songs with the band and was immediately hired to fill the vocalist position. Once recruited, LaBrie decided to drop his first name to avoid confusion with the other Kevin in the band. For the next few months, the band returned to playing live shows (still mostly around NYC), while working on vocal parts for the music written before acquiring LaBrie. Derek Shulman and Atco Records (now East West), a division of Elektra Records, signed Dream Theater to a seven-album contract based on a three-song demo (later made available as "The Atco Demos" through the Dream Theater fan club).

The first album to be recorded under their new record contract was Images and Words (1992). For promotion, the label released a CD single and video clip for the song "Another Day", but neither made significant commercial impact. The song "Pull Me Under", however, managed to garner a high level of radio airplay without any organized promotion from the band or their label. In response, ATCO produced a video clip for "Pull Me Under", which saw heavy rotation on MTV. A third video clip was produced for "Take the Time", but it was not nearly as successful as "Pull Me Under".

The success of "Pull Me Under", combined with relentless touring throughout the U.S. and Japan, caused Images and Words to achieve gold record certification in the States and platinum status in Japan. A tour of Europe followed in 1993, which included a show at London's famed Marquee Club. The show was recorded and released as Live at the Marquee, Dream Theater's first official live album. Additionally, a video compilation of their Japanese concerts (mixed in with documentary-style footage of the off-stage portion of the tour) was released as Images and Words: Live in Tokyo.

Awake and Kevin Moore's departure (1994–1995)
Eager to work on fresh material, Dream Theater retreated to the studio in May 1994. Awake, Dream Theater's third studio album, was released on October 4, 1994. Shortly before the album was mixed, Moore had announced to the rest of the band that he would be quitting Dream Theater to concentrate on his own musical interests, since he was no longer interested in touring or the style of music which Dream Theater performed. As a result, the band had to scramble to find a replacement keyboardist before a tour could be considered.

Former Yngwie Malmsteen and Dio keyboardist Jens Johansson, who would go on to become a member of Stratovarius, was among the biggest names to audition, but the band members were eager to fill the position with keyboardist Jordan Rudess. Portnoy and Petrucci had come across Rudess in Keyboard Magazine, where he was recognized as "best new talent" in the readers' poll. The two invited him to play a trial gig with the band at the Concrete Foundations Forum in Burbank, California. Although the show was a success, and Rudess was asked to fill the keyboardist position permanently, he opted to tour with The Dixie Dregs instead, since it granted him more personal latitude. Dream Theater hired fellow Berklee alumnus Derek Sherinian, who had previously toured and recorded with Alice Cooper and KISS, to fill in for the Waking Up the World Tour. By the conclusion of the tour, the band decided to take Sherinian on as Moore's full-time replacement.

A Change of Seasons, Falling into Infinity (1995–1998)
Once again finding themselves with a new member, the band did not immediately start working on new material. Fans around the world, united on the YtseJam Mailing List (the most popular form of communication between Dream Theater fans at that point), had begun to put pressure on the band to officially release the song "A Change of Seasons". This had been written in 1989 and was intended to be a part of Images and Words, but at almost 17 minutes, it was deemed too long for studio placement. It had nevertheless been performed live by the band, who continued to revise it in the years leading up to 1995.

The petition was successful, and the group entered BearTracks Studios in New York in May 1995 to rewrite and record the now 23-minute-long song with Sherinian contributing significantly to the final product. The band released A Change of Seasons as an EP along with a collection of cover songs from a live show recorded at Ronnie Scott's Jazz Club in London earlier that year.

After a brief run of small concerts and a short break, the band released a special Christmas CD through their official fan club, consisting of rare live tracks recorded during the band's early years. They continued releasing a new CD each Christmas until 2005.

Meanwhile, there were several changes at East West, and Dream Theater's main contact within the label was fired. As a result, the new team at the company were unaccustomed to the relationship Dream Theater had with former East West personnel, and they pressured them to write an album that was more accessible. In mid-1997, they entered the studio to write their next album. In addition to pressuring the band to adopt a more mainstream sound, East West recruited writer/producer Desmond Child to work with Petrucci on polishing the lyrics to his song "You or Me". The whole band substantially reworked the song, and it appeared on the album as "You Not Me" with a chorus that bore little resemblance to the original. Child also had a noticeable impact on the album, with a shift towards less complex and more radio-friendly compositions.

The band wrote almost two CDs worth of material, including a 20-minute-long follow-up to the Images and Words song "Metropolis–Part I: The Miracle and the Sleeper". The label, however, did not allow the release of a double album because it felt that a 140-minute record would not be well received by the general public. James LaBrie also felt that the CD should be a single disc. The unused songs were later released in the YtseJam Records release The Falling into Infinity Demos.

The material that made it onto the album proper was released as Falling into Infinity, which received a mixed reception from fans who were more familiar with the band's earlier sound. While the album was moderately progressive-sounding, tracks such as "Hollow Years" and "You Not Me" prompted some to believe it was the dawn of a new, mainstream-sounding Dream Theater. Overall, the album was both a critical and commercial disappointment. Although Portnoy did not speak out publicly at the time, he later revealed in the 2004 DVD commentary for 5 Years in a Livetime that he had been so discouraged during this period that he had considered disbanding Dream Theater altogether.

During the European leg of the Touring Into Infinity world tour, two shows were recorded for a live album titled Once in a LIVEtime, in France and The Netherlands. The album was released at around the same time as the video 5 Years in a Livetime, which covered the years from Kevin Moore's departure to the Falling into Infinity promotional tour.

Derek Sherinian's departure, addition of Jordan Rudess, and Metropolis Pt. 2: Scenes from a Memory (1999–2000)
In 1997, Magna Carta Records' Mike Varney invited Portnoy to assemble a progressive "supergroup" to work on an album, which would become the first in a long string of side-projects for the members of Dream Theater. The lineup consisted of Portnoy on drums, Petrucci on guitar, Tony Levin on bass, and keyboardist Jordan Rudess, who had finished with the Dixie Dregs. The band assumed the name Liquid Tension Experiment, and would act as a medium through which Portnoy and Petrucci could once again court Rudess to join Dream Theater. In 1999, he accepted an offer to become the third full-time Dream Theater keyboardist, replacing Sherinian.

With yet another new member, Dream Theater entered BearTracks Studio once again to write and record their next album. As a result of an ultimatum from Portnoy, the label gave the band complete creative control. The band began by revisiting the follow-up to "Metropolis–Part I", which had been partially written during the Falling into Infinity sessions but which had not been completed or used on that album. They decided to expand the 21-minute song into a complete concept album, with a story revolving around themes such as reincarnation, murder and betrayal. To avoid stirring up the fan base, a tight veil of secrecy enveloped the writing and recording process. The only things fans were privy to prior to its release were a track list that had been leaked against the band's wishes, and a release date. In 1999, Metropolis Pt. 2: Scenes from a Memory was released to high critical acclaim, being lauded as the band's magnum opus, despite only reaching No. 73 on the US album chart.

The album was mixed by David Bottrill, but only a few of his mixes made it on the final album. The bulk was remixed by Kevin Shirley, who had produced Falling into Infinity. The rest of the mixes can be heard in the band's official bootleg The Making of Scenes from a Memory.

The subsequent Metropolis 2000 world tour was by far their largest to date, and took over a year to complete. The concerts reflected the theatrical aspect of the album, with the first half of each show comprising the entire Scenes From a Memory album accompanied by a film showing dramatized portions of the story projected onto a video screen behind the stage. For the last date of the North American leg, at the Roseland Ballroom in New York City, actors were hired to play characters in the story, and a gospel choir was enlisted to perform in some sections of the performance. The show was filmed and eventually released in early 2001 as the band's first DVD release, Metropolis 2000: Scenes from New York, which was certified Gold in the US on November 8, 2002.

Since several songs from the second half of the four-hour show had to be cut from the DVD to save space, the band also released the full show on the live CD Live Scenes from New York. The original cover depicted one of Dream Theater's early logos (the Images and Words-era burning heart, modeled on the Sacred Heart of Christ) modified to show an apple (as in "Big Apple") instead of the heart, and the New York skyline, including the twin towers of the World Trade Center, in the flame above it. In an unfortunate coincidence, the album was released on the same date as the September 11 attacks. The album was quickly recalled by the band and was re-released with revised artwork later, although the few copies which were sold with the original artwork have since become rare collector's items.

Six Degrees of Inner Turbulence (2001–2002)
Putting the whole ordeal behind them, Dream Theater once again entered BearTracks Studios to record their sixth studio album. Four years after they first petitioned East West to allow them to release a double album, they finally got their chance with Six Degrees of Inner Turbulence. The first disc consisted of five tracks of 7–13 minutes in length, and the second disc was devoted entirely to the 42-minute title track, which remains to date the longest song Dream Theater has written. Many of the song's melodies and musical themes originated in an instrumental piece, written by Rudess, which would eventually become the song's "Overture". Those themes were then expanded by the rest of the band to form individual chapters in a complete story.

Six Degrees of Inner Turbulence was very well received by critics and the press. It was the most publicized of Dream Theater's albums since Awake, debuting on the Billboard charts at No. 46 and the Billboard Internet charts at No. 1. The subsequent world tour included a select few special "album cover" gigs (see Cover songs section, below), in which they played Metallica's Master of Puppets and Iron Maiden's The Number of the Beast in their entirety.

Train of Thought (2003–2004)
In 2003, Dream Theater entered the studio to write and record another album. Unlike Scenes from a Memory, which had been written and recorded simultaneously in the studio, the band took a different approach by setting aside three weeks for writing prior to recording. In the middle of the recording sessions for the album, a special tour with two other progressive metal bands, Queensrÿche and Fates Warning, was undertaken in North America. Referred to in the band's promotional material as the "Escape from the Studio American tour", the tour featured Queensrÿche and Dream Theater as co-headlining acts with Fates Warning performing supporting act duties. As a finale for each concert there was an extended encore in which both Dream Theater and Queensrÿche performed together on stage simultaneously, often playing cover songs.

At the completion of the tour, Dream Theater returned to the studio to finish the recording of their seventh album, Train of Thought. In contrast to the extended songs of their previous album, the band aimed to write a more song-oriented album, inspired in part by covering the Master of Puppets and Number of the Beast albums on their previous concert tour. Although the album was a critical success, its more straightforward metal sound alienated many of the band's existing fans, who had been attracted by the band's roots in progressive rock. During this time they also re-released their first two live videos for the first time on DVD, titled "Images and Words: Live in Tokyo/5 Years in a Livetime" on June 29, 2004, through Rhino Records. This release was certified Platinum on March 22, 2006.

Another world tour followed, named Train of Thought Tour. A modest North American tour was completed by the two bands, which Dream Theater supported Yes, a band which had been a major influence on their own musical style. After which Dream Theater continued to tour the world with their so-called "An Evening With Dream Theater" shows. The latter were captured in another live CD/DVD release, recorded at the famous Nippon Budokan Hall in Tokyo, Japan on their Train of Thought Tour. Live at Budokan was released on October 5, 2004, and was certified Platinum in the US on January 26, 2005.

Octavarium (2005–2006)
After their Train of Thought promotional tour, Dream Theater entered the Hit Factory studios in NYC to record their eighth album. They would in fact become the final group to use the famous studio, which closed on April 1, 2005.

Octavarium was released on June 7, 2005, and took the band's sound in yet another new direction. Its eight songs included a continuation of Portnoy's "Twelve-step" saga ("The Root of All Evil", steps 6–7 in the 12-step plan), as well as the title track, a musically versatile 24 minute epic rivaling "A Change of Seasons". Octavarium received mixed reviews from fans and has been the subject of spirited debate. Octavarium was the last album under their seven-album deal with Elektra Records, which had inherited the contract upon its absorption of EastWest Records.

Dream Theater started the Octavarium Tour extensively throughout 2005 and 2006 to celebrate their 20th Anniversary as a band, including a headlining spot on Gigantour alongside Megadeth and put together by frontman Dave Mustaine, also featuring Fear Factory, Nevermore and Symphony X. During a show on August 2, 2005, in Dallas, the band paid tribute to Pantera's late guitarist Dimebag Darrell by performing the song "Cemetery Gates" as an encore. In addition was the unexpected appearance of fellow musicians Russell Allen (Symphony X vocalist), Burton C. Bell (Fear Factory vocalist) and Dave Mustaine (Megadeth vocalist/guitarist), who joined the band on stage to perform parts of the song.

Dream Theater later departed from Gigantour 2005 a few dates before it ended and continued on with their own series of concerts, several of which were recorded and released for the band's fanclubs. The 20th anniversary tour concluded with a show at Radio City Music Hall in New York City on April 1, 2006. Though the show had minimal promotion, it was sold out days after tickets were made available. This show, which was recorded for a CD/DVD called Score released on August 29, 2006, through Rhino Records, featured songs from the band's entire history, as well a second half accompanied by a full symphony orchestra (the "Octavarium Orchestra"). This release was the band's third Live DVD release to be certified Platinum in the US on October 11, 2006.

Systematic Chaos and Greatest Hit (...And 21 Other Pretty Cool Songs) (2006–2008)
For the first time in their career, the band decided to take the summer off after their show at Radio City Music Hall. In September 2006, Dream Theater entered Avatar Studios to record their follow-up to Octavarium with legendary studio engineer Paul Northfield. Dream Theater's ninth studio album, Systematic Chaos, was released on June 5, 2007. The record marked their first with new label Roadrunner Records, which in 2010 would become a wholly owned subsidiary of the band's previous label Atlantic Records. Roadrunner implemented increased promotion for the album and Systematic Chaos duly reached number 19 on the Billboard 200. It also oversaw the release of a video for "Constant Motion" on July 14, the band's first music video since Hollow Years in 1997. The album was bookended by the two parts of "In the Presence of Enemies", written and conceived as a single piece but split into two halves for the purposes of the album. The other six tracks included the most recent part of Portnoy's continuing AA Saga with the song "Repentance".

In the same year, the first version of Rich Wilson's Lifting Shadows, an authorized history of the band's first twenty years, was released.

The 2007–08 Chaos in Motion Tour started off in Italy. Dream Theater played in the Gods of Metal concert on June 3, 2007, as well as various other European festivals including the Netherlands' Fields of Rock Festival, UK's Download Festival, the French festival Hellfest Summer Open Air alongside Megadeth, Korn, Mastodon and Slayer. The North American leg of the tour began on July 24 in San Diego, California and wrapped up on August 26 in Philadelphia, Pennsylvania. They played with opening acts Redemption and Into Eternity. The Chaos In Motion Tour continued for the rest of the year and into 2008, playing shows in Asia, South America and, for the first time, Australia.

On April 1, 2008, a two-disc compilation album titled Greatest Hit (...and 21 Other Pretty Cool Songs) was released by the band. The title jokingly references the song "Pull Me Under", the band's only significant radio hit. It also includes three song re-mixes from their second album, Images and Words, five edited versions of previously released songs, and a track from a single B-side. Unlike most greatest hits compilations, Dream Theater was actively involved with the album, coming up with the track listing that they felt best represented their musical careers.

After the release of Greatest Hit, drummer Mike Portnoy organized a new tour called Progressive Nation 2008. Unlike previous Dream Theater tours, performances were held in cities that they had not visited before in the past (such as Vancouver, British Columbia, Canada) or cities they had not played in for several years. This tour also marked the first time, since the release of Images and Words, where the group performed in small venues and performance halls.

In September 2008, the band released a DVD set called Chaos in Motion 2007–2008, featuring songs recorded at several shows during the Chaos in Motion tour.

Black Clouds & Silver Linings (2008–2010)
On October 7, 2008, Dream Theater returned to Avatar Studios to begin work on their tenth album, resuming their relationship with Paul Northfield to engineer and mix the record. The album, titled Black Clouds & Silver Linings, was released on June 23, 2009. In addition to the standard CD, the album was made available on vinyl LP, as well as a 3-disc Special Edition CD that includes the full album, a CD of instrumental mixes of the album and a CD of six cover songs from artists such as Queen and Rainbow. On July 1, 2009, the album debuted at No. 6 on Billboard's Top 200 album chart, with first week sales totalling 40,285, making their highest entry on the chart. The album featured "The Shattered Fortress", the last in Mike Portnoy's series of songs about his 12-step recovery from alcoholism, as well as the song "The Best of Times", described by Portnoy as "a real heavy personal subject about my dad who passed away during the making of the album ... He was battling cancer throughout its making."

The band also embarked on a second Progressive Nation tour, including the tour's first performances in Europe. Opeth, Unexpect and Bigelf supported Dream Theater in Europe, while Zappa Plays Zappa, Pain of Salvation, and Beardfish were slated to perform on the North American leg. However, Pain of Salvation and Beardfish were unable to tour with Dream Theater and Zappa Plays Zappa because of financial troubles within their respective record labels. The two new bands that filled the vacated slots for the Progressive Nation 2009 tour in North America were Bigelf and Scale the Summit with Bigelf performing on both European and North American legs.

After the Progressive Nation Tour, Dream Theater re-entered the studio to write and record a brand new instrumental track for inclusion on the God of War III soundtrack EP God of War: Blood & Metal. The track, titled "Raw Dog" (God (of) War reversed), marked the first time that the band has written and recorded an exclusive track for an outside project. "Raw Dog" includes the first ever commercially recorded harpejji track, performed by Jordan Rudess, as well as Dream Theater's final recorded performance with Mike Portnoy on drums. In December 2009, during their Black Clouds & Silver Linings tour whilst visiting Australia, Dream Theater appeared with one support act, Pain of Salvation. In March 2010, they toured South America with Bigelf. Afterwards, during the summer of 2010, Dream Theater supported Iron Maiden on the US and Canadian legs of their summer tour which were the last shows DT played during 2010.

Mike Portnoy's departure and arrival of Mike Mangini (2010–2011)
On September 8, 2010, drummer Mike Portnoy announced that he would be leaving Dream Theater, citing better relationships in other projects, burnout, and his desire for a break as reasons. Elaborating on the situation for MusicRadar, John Petrucci revealed that originally, Portnoy did not want to leave the band; he only wanted to take a five-year break. He eventually dropped this number to around one year. Only after the rest of the band rejected his proposal did Portnoy decide to quit.

After Portnoy left Dream Theater, relationships between him and his former bandmates became strained. In February 2011, Portnoy complained that no one from the band was returning his calls and e-mails. However, later Portnoy commented that both Petrucci and Rudess were the only members that stayed in touch with him. Tensions became especially high when Portnoy called James LaBrie "disrespectful" for comments LaBrie made during an interview, stating that Dream Theater were "not sad at all" that Portnoy was no longer a band member. By July 2011, LaBrie had not remained in touch with Portnoy. Portnoy later stated that he would rejoin the band in a heartbeat, stating: "They are the ones that have closed the door on it. I've only needed a break, and I've had that break. So I'm ready, willing and able. But I honestly don't think they ever will; they've closed their door on it and I think they're too headstrong in having to prove themselves without me. So I wouldn't count on it. But my door is always open."

A little more than a month after Portnoy's departure, Dream Theater began auditioning for a new drummer in New York City. The drummers who auditioned were Mike Mangini, Derek Roddy, Thomas Lang, Virgil Donati, Marco Minnemann, Aquiles Priester, and Peter Wildoer. Fates Warning drummer Bobby Jarzombek was also invited to audition, but had to turn down the offer due to scheduling conflicts. The candidates were notified whether they had been chosen on November 5; however, the results of the audition were not made public until April 2011 via a three-part YouTube documentary series called The Spirit Carries On. In the last episode of the series, it was revealed that Mangini was the drummer selected. Petrucci later explained that Portnoy approached them to rejoin after they had selected Mangini; Mangini however, by this time had left his job as a professor at Berklee and committed to Dream Theater full-time, so Portnoy's offer was rebuffed.

A Dramatic Turn of Events (2011–2012)
Dream Theater entered Cove City Sound Studios to begin working on a new album on January 3, 2011. Writing was completed on March 2 and done without Mangini. On April 14, LaBrie began tracking vocals and by June 28, the album's mixing and mastering by Andy Wallace were finished. Released worldwide on September 12 and in the United States on September 13, A Dramatic Turn of Events debuted at number one in some countries and attained the eighth position on the Billboard 200, the band's second ever top ten debut position on that chart after Black Clouds & Silver Linings. Although the album received mixed reviews, it won numerous awards from music publications and its lead single, "On the Backs of Angels", was nominated for Best Hard Rock/Metal Performance at the 2012 Grammy Awards, representing the band's first ever Grammy nomination.

Dream Theater kicked off their tour in support of A Dramatic Turn of Events on July 4, 2011, in Rome, Italy. The second leg of the tour took place in North America, where the band headlined with Trivium. After a short break to conclude 2011, the band returned to Europe with Periphery, to Asia with Andy McKee, to North America with Crimson Projekct and then to South America for the final leg of the tour. On August 19 and 20, two shows were recorded at Luna Park in Buenos Aires, Argentina for a live Blu-ray release by Over the Edge Productions. After a six-month delay, Live at Luna Park was released on November 5, 2013, by Eagle Rock Entertainment. The tour concluded on September 1, 2012, in Brasília, Brazil.

On December 25, 2013, at 06:00:00 EST, as a holiday gift to the fans, Dream Theater released a free electronic 2-CD set of live tracks that were not recorded for Live at Luna Park from their 2011–2012 tour in FLAC format via BitTorrent. The release date and time are an allusion to their 1994 song 6:00, the intro of which contains a repeated sample of the line "Six o'clock on a Christmas morning" as spoken by Helena Carroll in The Dead.

Dream Theater (2013–2014)
Writing for Dream Theater's twelfth studio album commenced on A Dramatic Tour of Events. During soundchecks, the band would jam and record their ideas, and John Petrucci would bring in material he wrote independently. Following the conclusion of the tour, the band took a break but continued writing. They reconvened in early 2013 to enter the studio.

In December 2012, Dream Theater re-signed with Roadrunner Records. The band's self-titled twelfth album was released on September 23, 2013, as part of the new agreement with Roadrunner. The album sold more than 34,000 copies in its first week and landed on the Billboard 200 chart at No. 7, the band's third consecutive top 10 album. In addition, the album cracked the top 10 in 24 countries including Japan, Germany, Argentina, The Netherlands, Finland, Italy, Switzerland, Canada, Denmark, Norway, Austria, Australia and United Kingdom. Dream Theater's seventh live album, Live at Luna Park, was released on November 5, 2013.

On July 8, 2014, Dream Theater released The Studio Albums 1992–2011, a box set spanning all albums from Images and Words to A Dramatic Turn of Events.

On September 30, 2014, Dream Theater released their eighth live album and film, Breaking the Fourth Wall, which was recorded live from The Boston Opera House on March 25, 2014. During this concert, the band were joined by the Berklee World Strings and the Berklee Concert Choir, directed by Eren Başbuğ, for the second half of the set. The set list for the tour featured the entire second half of Awake, in celebration of the album's 20th anniversary, including the song "Space-Dye Vest", which had never been performed live. The set list closed with a performance of four songs from Metropolis Pt. 2: Scenes from a Memory, in celebration of the album's 15th anniversary. The Along for the Ride Tour concluded on October 30, 2014.

The Astonishing and Images and Words anniversary tour (2015–2017)
On January 6, 2014, John Petrucci said that Dream Theater were already "planting seeds for album No. 13". He commented: "There are some song ideas and little things like that -- nothing really official, but the seeds just start to get planted. One of the great things about this career is that you have the opportunity every time to go in and start again with a blank slate and think, 'What can we do differently? How can we make this better? Where can we go from here?' Every album has a story, and to constantly have a fresh opportunity to do it is really satisfying."

The band headed into the studio in February 2015 to record its thirteenth album. The album, titled The Astonishing was released on January 29, 2016. It is a concept album set in a dystopian future society devoid of real music, centering on a conflict between a group of rebels and an oppressive empire. Two singles, "The Gift of Music" and "Moment of Betrayal" were released on December 3, 2015, and January 22, 2016, respectively.

Throughout 2016, Dream Theater went on a tour titled The Astonishing Live to support the album. They played the album in its entirety, with an intermission between the two acts, only playing songs from earlier albums on occasions later in the tour. Their performance was accompanied by a visual representation of the story on background screens. The band also made it a point to play at indoor theater halls such as Radio City Music Hall. In 2017, Dream Theater went on another tour, titled Images, Words & Beyond, to commemorate the 25th anniversary of Images and Words. Each night they performed the album in its entirety, as well as "A Change of Seasons", which was originally written during the Images and Words sessions, and other selections from their catalogue.

Distance over Time and Metropolis Pt. 2: Scenes from a Memory anniversary tour (2017–2019)
In a May 2017 interview with Rockbook, frontman James LaBrie talked about the style of the band's fourteenth studio album: "It's really important for us that the new album will be our best effort. It should be who we are at that particular moment. [...] But if along the way we feel that there is another album we should recognize once again, then we'll do it." In December 2017, Dream Theater announced that they had signed a worldwide longterm deal with Sony Music via Sony's progressive music label imprint Inside Out, for the release of the album.

The album was written in June and July 2018, and features pieces written collectively and lyrics written by Petrucci, Labrie, Myung and, for the first time ever, Mangini. In anticipation of the album, the band launched a "treasure hunt" in the form of an alternate reality game, where participants would search for various clues across the internet. The game ultimately led to a site revealing the title of the album to be Distance over Time. The site also revealed the cover art for the album, its scheduled release date in February 2019, as well as dates for a tour in North America celebrating the 20th anniversary of the band's fifth album Metropolis Pt. 2: Scenes from a Memory. On November 6, 2018, a press release from Inside Out officially announced Distance over Time, with a release date of February 22, 2019. Upon release, the album received widespread critical acclaim.

A View from the Top of the World and Lost Not Forgotten Archives (2020–2022)
In April 2020, Metal Addicts reported that Dream Theater was expected to begin working on their fifteenth studio album in 2021. About the direction of the album, guitarist John Petrucci stated in an August 2020 interview with Ultimate Guitar: "The eight-string project with Ernie Ball Music Man is something we are working on and hoping to have developed as this year goes on. I'm hoping that on the next Dream Theater record I'll be able to explore that." This would later be confirmed in an interview with Ultimate Guitar in February 2021. Also in August 2020, Petrucci also told Spain's Metal Hammer that the band would begin working on their new album in the fall. Recording sessions started at DTHQ (the band's own studio) in October 2020. The band was confirmed on November 27, 2020, to be writing the songs, while LaBrie was writing his parts back home in Canada. When asked in an interview, Petrucci said that the writing sessions were "off to a great start".

Petrucci released his first solo album in fifteen years, Terminal Velocity, on August 28, 2020. The album was recorded at DTHQ earlier the same year. Its recording sessions marked the first time in ten years that Petrucci worked with his former Dream Theater bandmate Mike Portnoy, who played drums on all tracks from the album. This collaboration led to speculation of a Dream Theater reunion with Portnoy, which was denied by Petrucci, who told Metal Hammer: "I understand where people are coming from with that. One of the concerns I had, a little bit – not musically at all – but about Mike, is I didn't want people to get the wrong idea."

On November 27, 2020, Dream Theater released their ninth live album, Distant Memories – Live in London, recorded at Hammersmith Apollo prior to the COVID-19 pandemic. On December 1, 2020, the band released the single "The Holiday Spirit Carries On", a medley of holiday songs played in a progressive metal style, exclusively through Bandcamp. The title references the fan-favorite song "The Spirit Carries On" from Scenes from a Memory. The proceeds from sales of the single benefited the band's road crew. On January 30, 2021, Dream Theater held a special streaming event titled Images, Words & Beyond Live in Japan, an online broadcast of a concert from the band's 2017 tour, which was originally recorded for Japanese television.

On May 5, 2021, Dream Theater announced a series of albums titled the Lost Not Forgotten Archives, the first release of which is the second set of the Images, Words & Beyond Live in Japan concert. The band added that the Lost Not Forgotten Archives will eventually include every YtseJam Records release on CD, vinyl and digital formats, along with previously unreleased archival material.

Dream Theater teased the new album on July 26, 2021, revealing that it would have seven songs, with more details to be released on July 28, 2021. On July 28, it was announced that the album was titled A View from the Top of the World, and it was released on October 22, 2021. The album was supported by five singles, "The Alien", "Invisible Monster", "Awaken the Master", "Transcending Time" and "Answering the Call", and music videos were released for each of them. The band promoted the album with a concert tour of Europe from April 20 to June 1, 2022. They had previously announced a tour of North America from late October to mid-December 2021 on the same day as the album, but announced on September 27 that it had been rescheduled to early 2022, due to safety concerns related to the COVID pandemic. The rescheduled tour began on February 2, 2022, in Mesa, Arizona.

On April 3, 2022, "The Alien" won a Grammy Award for Best Metal Performance, giving Dream Theater their first Grammy.

Upcoming sixteenth studio album, departure of Mike Mangini and return of Mike Portnoy, and Dominici's death (2022–present)
When asked in April 2022 by VW Music about the future of Dream Theater, keyboardist Jordan Rudess said, "After we get back from its last show of the European tour we have a bit of a break. And after I finish my solo shows, Dream Theater will continue on the road with some shows in Japan, South America, and more to be announced as we go. When that settles down, we'll be entering the studio again, and doing a new album, which will be awesome. So, yeah, stuff like that is on the horizon."

In October 2022, Petrucci stated that Dream Theater would begin recording their sixteenth studio album in late 2023. Two months later, LaBrie said that he did not "see [the band] going into the studio until the beginning of '24", adding, "I don't think it would make sense to be in there before then. But don't quote me on that. Some things always change."

On June 16, 2023, they started the Dreamsonic Tour, a travelling progressive metal festival which also featured Devin Townsend and Animals as Leaders. The tour ended on July 26. In August, John Petrucci mentioned that studio time for their sixteenth album was slated to begin in late 2023.

On October 25, 2023, Dream Theater announced the departure of drummer Mike Mangini as they were reuniting with his predecessor and founding member Mike Portnoy. The band also announced plans to record its first studio album with Portnoy in fifteen years. On November 17, 2023, it was announced that former lead vocalist Charlie Dominici had died at the age of 72.

In February 2024, Portnoy posted pictures from DTHQ on his Instagram account, confirming that a new Dream Theater album "is officially underway".

On April 2, 2024, John Petrucci and Mike Portnoy announced that all of the writing and the drum tracks were completed. John Petrucci posted a video on YouTube on May 1, 2024, confirming that the guitar tracks were completed. On June 26, 2024, Jordan Rudess announced on his Instagram that all the keyboards had been recorded.

Live performances


Throughout their career, Dream Theater's live shows have gradually become bigger, longer and more diverse. Prior to Portnoy's departure, Dream Theater "rotated" its set lists to ensure that fans who attended multiple shows in the same area would not see too many (or any) songs repeated. Portnoy, who constructed the set lists, would take into account the set list from the last time the band was in a particular city for the benefit of fans who saw the band on successive tours.

The band's full world tours, since Six Degrees of Inner Turbulence, have predominantly been "Evening with..." tours, in which the band performs for at least three hours without an opening act. Until 2012, such tours did not contain an intermission, but every tour since the Along for the Ride Tour in 2013–2014 until the Distance Over Time Tour had. The show that was recorded for Live Scenes From New York was well over three hours in length, and resulted in Portnoy almost being hospitalized after acquiring severe food poisoning from the food he ate before the show.

There is also a significant amount of humor, casualness, and improvisation attached to Dream Theater's concert. For example, the performance of "A Change of Seasons" on Live Scenes from New York features changes to a series of instrumental breaks, with Myung playing a baseball organ melody, Petrucci playing the opening theme to The Simpsons, and Rudess playing the ragtime section of "When the Water Breaks" from Liquid Tension Experiment 2 (the latter is also heard on the album Live at Budokan). Several songs included on Once in a LIVETime include snippets of others' pieces, such as Lynyrd Skynyrd's "Free Bird" and Rimsky-Korsakov's "Flight of the Bumblebee." Other quotations include "Mary Had a Little Lamb" during "Endless Sacrifice" on the Gigantour, a calliope-inspired break between verses of "Under a Glass Moon", a quote of "Don't Cry for Me, Argentina"'s main melody played by Petrucci while performing the intro solo of "Through Her Eyes" in Buenos Aires, the Turkish March at a concert in Istanbul, and the opening riff of Rush's "A Passage to Bangkok" at a show in Bangkok, Thailand. On the "20th Anniversary World Tour", Rudess has even thrown in a short "Twinkle, Twinkle, Little Star" theme in a break during "Endless Sacrifice," and during a concert in Israel he started a spontaneous "Hava Nagila", with the rest of the band later joining in. During the band's 2017 tour, a snippet of Metallica's "Enter Sandman" was played during Dream Theater's own song "As I Am".

Perhaps the best example of Dream Theater's unpredictable concert structure came during Derek Sherinian's time with the band. At selected shows the band members all swapped instruments and performed an encore as the fictitious band dubbed Nightmare Cinema. They usually performed a cover of Deep Purple's "Perfect Strangers," and, on one occasion, Ozzy Osbourne's "Suicide Solution," At some shows, Sherinian, Petrucci and Portnoy would take the stage together under the name "Nicky Lemons and the Migraine Brothers." Sherinian, wearing a feather boa and novelty sunglasses, would perform a pop-punk song titled "I Don't Like You" with Petrucci and Portnoy backing. During the Chaos in Motion tour, in several concerts before "Trial of Tears," Portnoy and Petrucci would change positions.

In the Score and Chaos in Motion DVDs, an animation has accompanied certain parts of the songs, showing the band playing along to the music as cartoon characters. On the Score DVD, during the song Octavarium, the band is seen performing in an octagonal shaped maze. As the animation continues Jordan Rudess spontaneously turns into Santa Claus and John Petrucci catches fire. In "The Dark Eternal Night" from the Chaos in Motion DVD, the band battles against a monster by shooting fireballs from guitars, throwing drum sticks, and screaming.

Shows and concerts
Dream Theater played and recorded a live performance at the Nippon Budokan Hall on April 26, 2004. It was later released as Live at Budokan on October 5, 2004.

Dream Theater's largest audience as a headlining act was 20,000 in Santiago, Chile on December 6, 2005. The show was released on DVD through Portnoy's YtseJam Records.

In 2007, after their show in Salt Lake City on July 30, Governor Jon Huntsman, Jr. signed a proclamation officially marking July 30, 2007 as Dream Theater Day in the state of Utah.

In 2008 Dream Theater started the Progressive Nation 2008 tour, along with Opeth, Between the Buried and Me, and 3. The tour is the brainchild of Mike Portnoy, who stated, "I've been wanting to assemble a package tour like this for many years now. With all of the festivals and package tours that go through America, I've been talking with our manager and agent for over 10 years now about doing something that focuses on the more progressive, musician-oriented side of hard rock and metal. I decided it was time to stop talking the talk, lace up and finally walk the walk."

On February 13, 2009, Dream Theater announced the official line up for their Progressive Nation 2009 tour. The tour was originally set to feature bands including Swedish bands Beardfish and Pain of Salvation, as well as Zappa plays Zappa. On June 22, 2009, Mike Portnoy announced that Pain of Salvation and Beardfish would not be touring the North American leg of the Progressive Nation 2009 tour because of record label complications. In the same announcement, Portnoy stated that the bands Scale the Summit and Bigelf would replace Pain of Salvation and Beardfish on the tour. This lineup change has put Bigelf on both the North American and European legs of the Progressive Nation 2009 tour. The tour's North American leg ran throughout July and August 2009. On March 26, 2009, it was announced that Dream Theater would take the Progressive Nation tour to Europe for the first time alongside Opeth, Bigelf and Unexpect. The tour ran throughout September and October 2009.

In June/July 2010 Dream Theater were the opening band for Iron Maiden during the first leg of their Final Frontier Tour which included Madison Square Garden as one of the many venues. On December 7, 2010, Dream Theater announced on their website that they would be headlining the High Voltage Festival alongside Judas Priest in 2011. In July 2011 they started A Dramatic Tour of Events to promote A Dramatic Turn of Events. In January 2014, they started the Along for the Ride Tour to promote their self-titled album. On December 13, 2016, Dream Theater confirmed 5 UK tour dates for their Images, Words & Beyond 25th Anniversary Tour, starting in Birmingham on April 18, 2017.

On March 4, 2022, Mike Portnoy attended his first Dream Theater show as an audience member at the Beacon Theatre in New York City, took photos with the band, and received a shoutout from James LaBrie during the show.

On April 22, 2023, Dream Theater announced the first edition of DREAMSONIC, taking place in North America throughout June and July and celebrating the summer's ultimate progressive metal line-up. Started in Cedar Park, Texas, on June 16, 2023, they were joined by special guests Devin Townsend and Animals As Leaders; the tour would be their final one with Mike Mangini.

On April 8, 2024, Dream Theater announced their first tour with Mike Portnoy in fourteen years, titled the "40th Anniversary Tour 2024 – 2025", which will begin with a month-long European leg in October.

Cover songs
Dream Theater have covered other artists' work throughout their career. They have performed cover songs live and in studio, with many of those live performances being recorded for official release. A Change of Seasons features Elton John, Deep Purple, Led Zeppelin, Pink Floyd, Kansas, Queen, Journey, Dixie Dregs and Genesis live covers. Through YtseJam Records, the band have also released full album live cover performances of Metallica's Master of Puppets, Iron Maiden's The Number of the Beast, Pink Floyd's The Dark Side of the Moon, and Deep Purple's Made in Japan. The special edition of Black Clouds & Silver Linings includes a bonus disc with Rainbow, Queen, Dixie Dregs, Zebra, King Crimson, and Iron Maiden covers. Other notable artists covered by Dream Theater include Black Sabbath, Ozzy Osbourne, Pantera, Rush, the Who, and Yes.

Logo and imagery
Despite the band being forced to change their name, Dream Theater adopted a custom logo (known as the Majesty symbol) and wordmark which has appeared on the vast majority of their promotional material and on the front cover of every Dream Theater studio album. The Majesty symbol is derived from Mary, Queen of Scots' mark, which was re-worked by Charlie Dominici for use on the album artwork for When Dream and Day Unite.

In September 2010, a fan of Dream Theater discovered that all of the letters of "DOMINICI" fit together perfectly into the Majesty symbol. When Charlie discovered this, he laughed and mentioned that "it only took them 25 years to figure out the 'Dominici Code!'" This has earlier also been discovered as shown on the comment section of DTFAQ and in the DTNorway Podcast Episode 2 from 2008, with Charlie Dominici.

Musical style
AllMusic's Stephen Thomas Erlewine described Dream Theater's music as a "dense blend of progressive rock and post-Halen metal". The band is well noted for being one of the early progenitors of the progressive metal genre, and they are considered a member of the so-called "big three" of the genre, along with Queensrÿche and Fates Warning. The original members, Mike Portnoy, John Petrucci and John Myung, have strong influences from progressive rock bands such as Rush, Yes, and Pink Floyd, heavy metal bands such as Iron Maiden and Judas Priest, various speed metal bands, and even the glam metal of the day. John Petrucci described Dream Theater's musical style as a blend of Rush, Led Zeppelin, Iron Maiden, Yes, and Metallica. While Mike Portnoy described Dream Theater's musical style as they're a blend of progressive rock and heavy metal. They encompass the progressive aspect, influenced by Rush, Yes, Pink Floyd, and Genesis, alongside the metal aspect influenced by Judas Priest, Iron Maiden, Metallica, and Black Sabbath. When combined, that's precisely what characterizes Dream Theater. This synthesis created a unique metal that was not traditional of the day: it had distorted guitars and fast riffing, but the music focused more on technical proficiency and precise execution than on heavy metal riffs. The band's music has focused on three main elements: metal, melody, and progressive roots. In the liner notes for the 2008 Greatest Hit compilation, Mike Portnoy cited artists such as Peter Gabriel, U2, and Journey as inspirations for Dream Theater's softer songs. Dream Theater's music has also been described as art rock.

Dream Theater's 2003 album Train of Thought showcased a heavier sound. This decision was inspired by the positive feedback received from their previous heavier songs on stage. 1999's Metropolis Pt. 2: Scenes from a Memory was praised for its display of old-fashioned progressive rock, and was influenced by classic conceptual rock records such as the Beatles' Sgt Pepper's Lonely Hearts Club Band, Pink Floyd's The Wall and The Final Cut, the Who's Tommy, and Genesis's The Lamb Lies Down on Broadway.

Dream Theater's music usually borrows elements from other musical styles including symphonic rock, symphonic metal, arena rock, soft rock, and classical music.
