The soundtrack to Forbidden Planet (1956) was a milestone moment in the history of electronic music. It was the first entirely electronic film score, composed by Louis and Bebe Barron using DIY circuitry inspired in part by Norbert Wiener's 1948 book Cybernetics: Or, Control and Communication in the Animal and the Machine, a seminal text in its own right. At the time that the film's producer at MGM, Dore Schary, met the Barrons they were beatnik musicians hanging out in Greenwich Village. The soundtrack to Forbidden Planet continues to astonish even today. (Listen to the "Main Title" at left.) My friend Ken Hollings, author of the fantastic outré history book "Welcome to Mars," created a wonderful audio documentary that just aired on BBC Radio 3 about the Barrons and their iconic "electronic tonalities."
