Ryoji Ikeda (born 1966 in Gifu, Japan) is a Japanese sound artist who lives and works in New York City. Sometimes harsh, sometimes remarkably gentle, Ikeda's music is concerned primarily with sound in a variety of "raw" states, such as sine tones and noise, often using frequencies at the edges of the range of human hearing. The conclusion of his album +/- features just such a tone; of it, Ikeda says "a high frequency sound is used that the listener becomes aware of only upon its disappearance" (from the CD booklet). Rhythmically, Ikeda's music is highly imaginative, exploiting beat patterns and, at times, using a variety of discrete tones and noise to create the semblance of a drum machine. His work also encroaches on the world of ambient music; many tracks on his albums are concerned with slowly evolving soundscapes, with little or no sense of pulse.
In addition to working as a solo artist, he has also collaborated with, among others, Carsten Nicolai (under the name "Cyclo.") and the art collective Dumb Type. His work matrix won the Golden Nica Award in 2001.
In 2004, the dormant Saarinen-designed TWA Flight Center (now Jetblue Terminal 5) at JFK Airport briefly hosted an art exhibition called Terminal 5 curated by Rachel K. Ward and featuring the work of 18 artists including Ryoji Ikeda. The show featured work, lectures and temporary installations drawing inspiration from the idea of travel — and the terminal's architecture. The show was to run from October 1 2004 to January 31, 2005 — though it closed abruptly after the building itself was vandalized during the opening party.
