In the long interview that forms the body of this publication, Éliane Radigue talks about her work, her reflections and underlying research, as well as her historical context. The publication also contains a commented list of works and Radigue's programmatic text on The Mysterious Power of the Infinitesimal.

Éliane Radigue (born 1932 in Paris) is considered one of the most innovative and influential contemporary composers, from her early electronic music through to her acoustic work of the last fifteen years. Influenced by musique concrète and shaped by regular sojourns in the United States, where she discovered analogue synthesisers, her work unfolds an intensity which is at once subtle and monumental. Through her deep reflections on sound and listening, not only her music but also her working methods have come to shape a widely resonating set of new parameters for working with sound as musical material.
