James Tenney: Changes - 64 Studies for 6 Harps
Changes: 64 Studies for 6 Harps (1985) is a large-scale work that combines and connects many of James Tenney's (1934 - 2006) most important theoretical and musical ideas, including gestalt segregation principles and complex intonation systems. Composed with the aid of a mainframe computer at York University, the piece also marks a return to computer-aided, algorithmic composition after a long hiatus.

This recording is from a 1980 solo seventy-minute improvisatory concert in Zürich, a cherished cassette made by a friend of Eastman's, who recently realized its uniqueness and decided that he should share it.
