Passages is a collaborative chamber music studio album co-composed by Ravi Shankar and Philip Glass, released in 1990. The album is a hybrid of Hindustani Classical music and Glass' distinct American minimal contemporary Classical style.
A collaboration between an avant-garde modern Classical composer and a traditional Indian/Hindi composer/performer seems pretty unlikely. However, Passages works splendidly. Shankar's smooth style fits nicely with Glass' dissonant orchestrations.
