t. nakamura

Toshimaru Nakamura has been producing electronic music
on self-named "no-input mixing board," after long unhappy
years with the electric guitar. The name describes the method
of his music. "No" external sound source is connected to «inputs» of the "mixing board." Mostly an improviser,
occasionally a composer for dancers, an instrumentalist
for compositions.
