Ryoji Ikeda (JP/FR) is an electronic composer.
Ryoji Ikeda is Japan's leading electronic composer. He focuses on the minutiae of ultrasonics, frequencies and the essential characteristics of sound itself. His work exploits sound's physical property, its causality with human perception and mathematical dianoia as music, time and space. Using computer and digital technology to the utmost limit, Ikeda has been developing particular "microscopic" methods for sound engineering and composition. Since 1995 he has been intensely active in sound art through concerts, installations and recordings: the albums +/- (1996), 0 degrees (1998) and Matrix (2000) have been hailed by critics as the most radical and innovative examples of contemporary electronic music.
