Tibetan Bells 2
Wolff and Hennings' first album, Tibetan Bells, created a stir  when it was released in 1971. It represented a pioneering style of music,  unfamiliar to an audience experienced only in Western modes of composition  and instrumentation. In 1978, they recorded Tibetan Bells II in San  Francisco. The subsequent contribution by Wolff and Hennings to the Philip  Glass soundtrack for `Koyaanisquatsi', an avant-garde film, brought the  bells before a new audience.
