Ryoji Ikeda is a renowned producer and composer of S/N and OR for the multimedia art group Dumb Type in the early 1990s. Working convincingly across both visual and sonic media, Ikeda gained reputation as an interd isciplinary media artist. His installations and performances offer the experience of trans-digital immersion with sound sculptures. He uses sine waves, white noise and dramatic visible digital projections that display micro transformations of both pixels and data. The sine wave is a continuum of total purity and predictability, and white noise expresses total randomness. The installation sphere places the audience in a unique position between these two sound territories. Throughout his long-term projects like datamatics (2006) and testpattern (2008), he exposed critical points beyond the human perception of sounds that occupy the world, visible elements and data. Ikeda built recognition as a global artist through participating in experimental exhibitions at the Transfinite at Park Avenue Armory in New York 2011 and db convened at Hamburger Bahnbof earlier this year. Mediacity Seoul 2012 presents data.matrix (n°1-10) which is composed of 10 video projections and sound sources. This work was first shown at the Museum of Contemporary Art Tokyo where he used pure data for sound, visual patterns sources that derive from hardware errors and software codes. With delicate and powerful layers of sound and graphics visualizing data, the audience can experience absorption into the mimetic world of matter, time and space.
