100% (band)


100% (Hangul: 백퍼센트) is a 7-member South Korean boy group that debuted in September 2012 under Andy Lee’s company T.O.P Media with their first single album We, 100%.



In 2009, 100% member Rockhyun – under his stage name Rocky (Hangul: 로키) – was one of the two members of Andy Lee’s boy group Jumper (Hangul: 점퍼), which promoted two singles, “Yes!” (feat. Eric) and “Dazzling Eyes” (Korean: 눈이 부셔) (feat. Kang Ji-young of Kara).

The same year, Minwoo was featured during Andy’s promotion for his song “Single Man”, along with Jumper’s second member Park Dong-min (Hangul: 박동민).Minwoo has also been active as an actor. He starred in KBS2’s 2006 drama Sharp 3 (Korean: 반올림3), SBS’s 2007 drama The King and I (Korean: 왕과 나) and in two movies, Crazy Waiting (Korean: 기다리다 미쳐) (2007) and Where Are You Going? (Korean: 특별시 사람들) (2009).

2012: Debut

100% were first introduced to South Korea’s TV audience in SBS MTV’s variety show Teen Top Rising 100% (Korean: 틴탑의 뜬다 백퍼), in which they starred alongside fellow T.O.P Media artist Teen Top and their founder Andy Lee of Shinhwa. The show aired ten episodes between June 16 and August 18, 2012.

In late 2011 already, before 100%’s official debut, a collaboration with labelmate Teen Top was planned, but no further information regarding this matter was ever released and the project was not put into action.

On September 13, the group was the first featured group on Arirang TV’s Pops in Seoul’s new segment, New Star.com. This was followed by the release of two music video teasers on their official YouTube channel on September 13 and 16, showing the seven members dancing in a barren desert and junkyards. Their debut single album We, 100% was released on September 18. It consists of three tracks and one instrumental version, which were all written and produced by Super Changddai. The same day, the music video for its lead track “Bad Boy” (Korean: 나쁜놈) went online on the band’s official YouTube channel. 100% made their official debut performance of “Bad Boy” on September 21, 2012 on KBS Music Bank, followed by MBC Music Core and SBS Inkigayo that same weekend.
