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. 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." Nakamura's music has been described as "sounds ranging from piercing high tones and shimmering whistles to galumphing, crackle-spattered bass patterns." Nakamura has recorded solo albums, and has collaborated with Yoshihide Otomo, Keith Rowe, and Nicholas Bussmann among others.
