Ryoji Ikeda

The world reduced to data
The "aesthetic of data" and how it shakes up human perception

Ryoji Ikeda has gathered worldwide attention with his elaborately composed musical compositions of sine wave, pulse and other minimal components of "sound". In this performance on the theme of "data" forming our perception of the world, Ikeda presented a concert piece utilizing a wide variety of data derived from the realms of mathematics, economics, biology and nature.
The title "C4I" is basically the name of a communication/information processing system for command and control in military operations. In addition to this meaning, here it integrates keywords expressing the various aspects of data. Through this work, made up of sounds and visuals pushing the limits of perceptibility in terms of resolution and speed, Ikeda connected his audience directly to the world, and highlighted the ubiquitous presence of data while exhibiting their multifaceted nature.

C4I (Commissioned by YCAM / World Premiere)

Ryoji Ikeda

Sceneries of a new world formed by images and sounds

This work themed around and incorporating data in vast amounts and huge varieties combines aspects of a concert piece and movie.
Appearing one after another on a large screen on the stage are images of exquisite natural landscapes transforming into an abstract language (data), as well as graphics, series of numbers, and quotes from various text sources with a strikingly realistic impact. The visuals are perfectly synchronized with accompanying sounds, to present the spectator with an overwhelming view blending elements of nature, science and philosophy.

This is the newest version of "formula", a piece that has been touring around the world since it was first unveiled in 2000.
Sine wave, pulse, white noise and other sounds that Ikeda has been making maximum use of in his unique approach, are elaborately integrated with images mixing abstract graphics and large amounts of live-action sequences running at high speed, to take the audience on a journey to a totally new domain of perceptual experience.
