Led Apple

Led Apple (stylized as LEDApple) was a South Korean rock band formed by StarKim Entertainment in 2010. The band's final lineup consisted of Seo Youngjun (Jun), Lee Kyumin (Kei) and Kim Hyoseok (AKi)

The part "Led" in LEDApple stood for "Logic Egoism Delete" and was promoted during their debut but they stopped referring to it since their CODA mini-album was released. Instead they replaced it with a practical explanation of "shining as brightly as LED whenever they perform" which was eventually referred to as a tribute to their role-model, Led Zeppelin. The word "Apple" in the band's name is supposed to represent their fresh image as idols and fresh music that they release. On August 16, 2015, it was announced that the band would be changing their name to LedT starting on September 1, 2015.

The band made their debut on October 6, 2010, with their promotional single, "Dash" (대쉬), a remake of Baek Ji-young's song of the same name. Since their debut, the band have released six singles and three mini-albums. The band disbanded March 6, 2016.

2010–2011: Debut and line-up changes
Prior to debut, member Minyong had been a contestant on the show Superstar K. The band was first revealed on September 27, 2010, as a five-member group and marketed as a new "idol rock band". The teaser for their debut single was released on September 29. On October 6, 2010, Led Apple performed their debut promotional single "Dash", which is a remake of a song originally sung by Baek Ji-young at the Busan International Film Festival and the music video was released the next day. The band's single was released alongside their single album, Logic Egoism Delete. They later performed the promotional single on November 11, 2010, on Mnet's M! Countdown as their debut stage.

On February 1, 2011, member I-OH announced his departure from the group on Twitter due to tuberculosis, however he did state that he would remain with the company. Vocalists of the group Minyong and Sunghyun later left for personal reasons that were not publicly revealed. Three new members joined the band for the release of their mini-album, Niga Mwonde (니가 뭔데; lit. Who Do You Think You Are); Hyoseok, Jaehoon and Kyumin with Jaehoon becoming leader of the band. On June 13, 2011, the band released a comeback teaser for their mini-album and title track of the same name. However, the teaser was criticized for featuring the band in a club and drinking alcohol. Three members of Led Apple were minors at the time, and so the teaser was considered a bad influence towards youths.

The band's first mini-album, Niga Mwonde and lead single of the same name were released on June 15, 2011, alongside two different music videos; a regular version and a drama version. However, the band faced another controversy after many internet communities claimed that Led Apple's single "Niga Mwonde" had plagiarized CN Blue's song, "Love". However, Starkim Entertainment later released a statement addressing the plagiarism issue, stating that both songs were composed by Lee Sang-ho which is why they sounded similar.

On July 19, 2011, Led Apple released their second promotional single from the mini-album Niga Mwonde, "Birthday Killer". The song was released in an attempt to make anti-fans realise that their hate comments can cause idols to do extreme things out of their misery. The music video was praised for being "powerful" in bringing out a message by critics and fans alike. However the song was not a commercial success and didn't manage to peak within the top one-hundred on the Gaon Chart.

After ending their promotions for the Niga Mwonde mini-album, leader Jaehoon left the band citing personal reasons; no other information was disclosed. On October 28, 2011, the band announced a new member would be joining them for their upcoming single, Keon U who is well known as the son of famous composer, Park Kwang-hyun. Another new member, Hanbyul was also announced on November 3 as the new appointed leader of the group alongside teaser photos of the rest of the band, thus making them a six-member group.

On November 7, the teaser for their next mini-album, CODA was released and it also revealed Led Apple's new sci-fi concept. An extended nine-minute version of the teaser was also released on November 9 and was dubbed the "drama teaser". The music video for their next single, "Eojjeoda Majuchin" (어쩌다 마주친; lit. Ran Into You By Chance) was released on November 11 and it featured former SeeYa member, Nam Gyu-ri as a cyborg and love interest in the video. In the week beginning December 2, the band's mini-album, CODA managed to reach an impressive number six on the Gaon Chart. On December 15, 2011, Led Apple was nominated for the "Anticipated Super Rookies for 2012" award at the Wave K Super Rookies Awards. The band managed to achieve the third highest number of votes for the award losing out to RaNia and B1A4, respectively.

On March 16, the band made their Japanese debut after attending the K-Rookies Party, Vol. 1 concert that took place in the Nakano Sun Plaza in Tokyo, Japan. The band performed four of their songs as part of the concert's finale and later expressed their desire to come back to Japan during the press conference.

After ending their promotions for "Sadness", the group announced that they would be holding their first solo concert titled, Now Playing – Led Apple in Seoul, Vol. 1.
