Mucc (Japanese: ムック, Hepburn: Mukku, officially romanized as MUCC) is a Japanese visual kei rock band, formed in Ibaraki in 1997. Named after a character from the children's TV show Hirake! Ponkikki, the band is also known by the nickname 69 since "six nine" can be pronounced "muku" in Japanese. As of 2015, the band has released twelve studio albums, two live albums, three EPs, thirty-three singles and seventeen home videos, some of which were also released in Europe.
Formed in 1997 by Miya, Tatsurou (then called "Tattoo"), Satochi and Hiro, they originally played The Blue Hearts and Glay covers. In 1999 Hiro left and was replaced by Miya's childhood friend Yukke. In December Mucc made their first official release, the EP Antique. They released their first album, Tsūzetsu in January 2001. In 2002 they signed to Danger Crue, but to their own sublabel Shu, and released their second album Hōmura Uta.
Mucc debuted in Europe in August 2005, including a performance at Wacken Open Air. The following year, they performed in the United States at the Otakon anime convention. They returned to the United States in 2007 for the JRock Revolution Festival.
