Ryoji Ikeda began exploring experimental music in the 1980s when he was a part of the Japanese artist collective group, Dumb Type, whose complex installations criticize the expansion of digital technologies. In these installations using transitory systems, sound and light are mathematical objects; the viewer follows their manipulations. For the Centre Pompidou, the artist has created a double installation, an immersive journey—with both visual and sonic elements—where the visitor’s sensorial experience is at the heart of the system.
