An Echo That's Reversing

Vladimir Ussachevsky and Otto Luening performed a concert of new electronic music on 28 Oct 1952 at the Museum of Modern Art. From Paul Griffiths’ Modern Music and After:

The Russian-born Vladimir Ussachevsky (b. 1911), who taught at Columbia University, gave a demonstration of the new medium’s potential in 1952, and he was soon joined in his endeavours by Otto Luening (b. 1900), who had studied with Busoni. They presented the first concert of electronic music in America, at the Museum of Modern Art in New York on 28 October 1952: representative of the pieces then heard are Ussachevsky’s Sonic Contours and Luening’s Fantasy in Space, based on the sounds of piano and flute respectively. Out of their efforts grew the Columbia-Princeton Electronic Music Center, which was formally founded in 1960.
