Toshimaru Nakamura is a Japanese musician, active in free improvisation and Japanese onkyo.
He began his career playing rock and roll guitar, but gradually explored other types of music, even abandoning guitar and started working on circuit bending. He uses a mixing console as a live, interactive musical instrument: "Nakamura plays the 'no-input mixing board', connecting the input of the board to the output, then manipulating the resultant audio feedback."
