In 1971, in association with West German Television, we produced a documentation on New York's musical avant-garde that was broadcast only in Germany at the time of its release. In 2010, nearly 40 years after the film's original production, it felt desirable to recycle the performances and interviews with the featured composers in order to create a revealing look back to those years for an English-speaking audience. Featuring notable contributors to the musical avant-garde such as John Cage, Philip Glass and Ben Patterson, this portrait explores experimental sound and the rise of electronic composition. "New Music: Sounds and Voices from the Avant-Garde, New York 1971" offers valuable insights into the nature and issues of advanced composition at the beginning of the 1970s.
