Louis and Bebe Barron were early pioneers in electronic music. They created the first entirely electronic score for a film with this soundtrack for Forbidden Planet. You hear ossilators, filters, mixers and all kinds of electronic noise. When I first watched the film as a child I was most interested in the soundtrack, it was totally unlike anything I'd heard before or since. When you consider that it was made in the 1950's it's amazing to think how ground-breaking this was. It's one of the key pieces in the development of electronic music. Some people may quibble on whether this should be classed as "music". However this CD has a strong emotional effect on me. This music can be completely unsettling to terrifying but sometimes warm as well. All music should provoke an emotional response. This is an amazing CD and is highly recommended whether or not you are a fan of the film.
