USSACHEVSKY, VLADIMIR (ALEXIS)

born Nov. 3 [Oct. 21, Old Style], 1911, Hailaer, Manchuria died Jan. 4, 1990, New York, N.Y., U.S. Russian-born American composer known for his experiments with music for the tape recorder, often combined with live sound. The son of Russian parents, Ussachevsky entered the United States in 1931 and thereupon studied at Pomona College, Claremont, Calif., and at the Eastman School of Music of the University of Rochester, Rochester, N.Y. In 1951 he began experimenting with tape composition, and in 1953 he began collaborating with the composer Otto Luening (q.v.). This fruitful partnership resulted in a number of works incorporating tape recorder and conventional instruments. In addition to works written with Luening, his compositions include Sonic Contours (performed 1952) for tape and instruments; a piano concerto; and orchestral, choral, and chamber works. He also wrote tape scores for George Tabori's film version of Sartre's play No Exit (1962) and for a television documentary, An Incredible Voyage (1968). In 1968 he began working in computer music. He taught music at Columbia University from 1947 to 1980, and in 1959 he helped found the ColumbiaPrinceton Electronic Music Center, New York City.
