From 1994 to 1997, as a member of Ground Zero (which disbanded in March 1998), Sachiko M performed at festivals and concerts around the world. She played an important role in the group's chopped-up, "plunderphonic" (or "plagiaristic" sampling) sound. Since the disbanding of Ground Zero, Sachiko M has pursued a unique performance style which brings to the forefront the sampler's own test tones and noise, to develop nearly memory-free sampling works. Her solos consisting entirely of sine waves have attracted a great deal of attention. In addition to playing solo, she often collaborates with musicians around the world as well.
