I wasn't hallucinating. It was the Who -- or more specifically, Pete Townshend -- who had the idea of feeding people's brain waves into a synthesizer to create individual themes. This was the cornerstone of the Lifehouse project, a rock opera that never quite took off.

I still think it would be interesting to monitor people's brain waves while they're listening to various types of music.
