Ryoji Ikeda (池田 亮司 Ikeda Ryōji, born 1966) is a Japanese visual and sound artist who lives and works in Paris. 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. Ryoji Ikeda was born in Gifu, Japan in 1966. 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 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. In May – June 2011 a presentation of three of the artist's immersive audio/visual projects, The Transfinite, was exhibited at the Park Avenue Armory. In 2014, Ikeda was awarded the Prix Ars Electronica Collide@CERN 2014. As a result, he began his residency at CERN in July 2014 until 2015, during which he developed supersymmetry and micro | macro.
