Henry Wolff and Nancy Hennings first encountered these instruments during a 1969 trip to India and Nepal where they studied with the Kagyu branch of Tibetan Buddhism. Since 1971, the duo has been releasing a subtle, haunting series of recordings featuring Tibetan bells, including a collaboration with Grateful Dead percussionist Mickey Hart called Yamantaka. Wolff and Hennings also contributed their skills to the Philip Glass soundtrack for the film Koyaanisqatsi, which brought the transcendent sound of the bells to wider audiences. The uncanny resonances of these acoustic instruments produce music that often sounds electronically generated. ~ Linda Kohanov
