gets stroked by Robby the Robot

The 1956 sci-fi thriller Forbidden Planet was the first major motion picture to feature an all-electronic film score -- a soundtrack that predated synthesizers and samplers. It was like nothing the audience had seen -- or heard. The composers were two little-known and little-appreciated pioneers in the field of electronic music, Louis and Bebe Barron.

Married in 1947, the Barrons received a tape recorder as a wedding gift. They used it to record friends and parties, and later opened one of the first private sound studios in America.
