fm6 writes "NPR has a story up about the first musicians to compose electronic music. In 1947, Louis and Bebe Barron received an early tape recorder as a wedding present. About the same time, Louis Barron became interested in Norbert Wiener's book Cybernetics and its thesis of common elements in living and artificial systems. This led the Barrons to create a new kind of music using electronic circuits and painstakingly edited magnetic tapes. The Barrons music was featured in various avant-garde records and movies, and finally reached a mass audience in the Science Fiction classic Forbidden Planet."
