Here is a catalogue raisonee of Stockhausen's complete output, involving no technical analyses, but rather an examination of the music's aesthetic, practical, and intellectual assumptions. The book contains plentiful citations from the history of radio, film, and sound recording, and from contemporary science and technology. Laid out in strict chronological order, it contains unusually ample commentary on the composer's sources of inspiration, including discussions of the composers Hermann Schroeder, Olivier Messiaen, Pierre Schaeffer, Herbert Eimert, John Cage, the information scientist Werner Meyer-Eppler, and structural anthropologist Claude Levi-Strauss. Each of Stockhausen's compositions is treated on its own terms, and also as a piece in a larger puzzle, embracing surrealist art and literature as well as music. Every piece of music is fully documented within the text with full information of the publisher, catalogue number, instrumentation, duration, and composer-authorized compact disc.
