This isn’t well known because his name was (deservedly) mud at the time, but Timothy Leary did a lot of work with sound and lights. He did his light shows when he was a pop guru, but he was even doing this work before he got fired from Harvard.

At the time, he considered it following the history of altered states. In the nineties when he had mellowed out, Leary started talking about lights, sound and technology. Here’s one example:

I’ve had a few experiences with non chemically induced altered states. They’re psychedelic-ish, but not really comparable to a substance like psilocybin.

They’re both altered but very different.
