Japanese band, formed in Tokyo in 1987. They incorporate elements of prog-rock, hardcore, heavy metal and noise-rock in their music. The core members are KK. Null (who is also known for his solo works) and Mitsuru Tabata (who is mostly known for his work with Acid Mothers Temple), the rest of the line-up went thru several changes over the years. They reformed in 2007 after a long break and started to tour again in 2009, joined by Tatsuya Yoshida on drums, who was also a part of one of the early line-ups. Tabata left the band in 2012, so currently they work as a duo.

Current line-up:
KK. Null - vocals, guitar
Tatsuya Yoshida - drums, vocals
