Members: Sudoh Toshiaki, Yui Kimijima

Japanese experimental improvisation duo formed in winter of 1997 consisting of Sudoh Toshiaki who performed drums and Yui Kimijima who recorded the drums with microphones and manipulated the recordings in real time. During live performances, they were occasionally accompanied by guest artists such as Merzbow, Otomo Yoshihide, Toshimaru Nakamura, and Yutaka Fukuoka. They have performed on and off, performing in 2010 after a five-year hiatus. All recordings by the band are produced live with minimal overdubbing.
