Born in 1966, Japan\'s leading electronic composer Ryoji Ikeda (池田亮司) 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.
