"Bebe" and her husband "Louis Barron" were two American pioneers in the field of electronic music. They are credited with writing the first electronic music for magnetic tape, and the first entirely electronic film score for the MGM movie "Forbidden Planet"(shared here).
This soundtrack for "Forbidden Planet" is today recognized as the first entirely electronic score for a film. Eerie and sinister, the soundtrack was unlike anything that audiences had heard before. Music historians have often noted how groundbreaking the soundtrack was in the development of electronic music.
