Featuring audio material recorded between 1989 and 1999 and compositions created between 2013 and 2022, »ultratronics« explores sound's arithmetical and computational essence and renders them into the propulsive auditory experience that constitutes Ikeda's sound signature.

Ryoji Ikeda has created numerous immersive works that dynamically combine technology, light, and sound to electrify the audience’s senses. Since 2000 Ikeda has pursued the theme of data, with a particular interest in the fields of genetics, quantum physics, and astronomy, which he has incorporated into works that present new ways of perceiving the world in numerical terms. To be experienced visually and aurally, the album transports the listeners in a world composed of large amounts of data that usually go unnoticed.
