“This edition of The Morning Concert features Parisian composer Eliane Radigue. Host Charles Amirkhanian explores Radigue’s background as a student of Pierre Schaeffer and Pierre Henry, her compositional technique involving synthesizers and tape recorders, and her life as a composer and Tibetan Buddhist. Radigue discusses the compositional and performing processes involved in her “combinatory” music, and explains how she has adapted to the lack of acceptance of her music in Paris. Radigue performs two pieces live in the studio: Chry-ptus and Triptych. This radio performance constitutes the world premiere of the first and third movements of Triptych”
