Ryoji Ikeda, born 1966 in Gifu, is a leading figure in contemporary Japanese art music, and the proudowner of an unusually large international fanbase, considering his genre. His compositions aregenerated using raw, artificial sounds (sine waves, clicks, glitches, white noise), often constructed tocreate drum-machine like patterns; he also frequently uses tones outside the range of human hearingto subliminally alter the listener's perception of the music.
