Ussachevsky (1911-1990) was a pioneer in electronic music who composed and taught at the Columbia-Princeton Electronic Music Center. Before 1952 his music was neo-Romantic. After 1952 he composed mostly using electronic instruments and computers. He produced the first works of “tape music,” a uniquely American synthesis of the French musique concrète and the German pure electronic schools. With Otto Luening, he co-founded the Columbia-Princeton Electronic Music Center in 1959 and directed its course for the next twenty years as the leading electronic music studio in the United States.
