Toshimaru Nakamura is a Japanese musician active in free improvisation, noise and Japanese Onkyo. Pioneering the use of no-input mixing board as a performance instrument in the mid-1990’s, he has since then appeared on over one hundred audio publications, including nine solo CD’s. He has collaborated with artists including Sachiko M, Otomo Yoshihide, Keith Rowe, John Butcher, Espen Reinertsen, Nicholas Bussmann, Taku Sugimoto, Tetuzi Akiyama, dancer Kim Ito, and drummer Jason Kahn.
As an active organizer of concerts in Tokyo, Nakamura has helped many musicians coming to Japan find places to perform, both with himself and with others. The series he has organised since 1998 were crucially important in exposing a new manner to improvised music (referred to as Electro Acoustic Improvisation) to the Japanese public and to foreign musicians visiting Japan, making Tokyo one of the global hotspots for this new approach to music.
