I like to listen to, on drugs, the following. Plus more probably.

Pink Floyd, The Dead, The Who, Allman Brothers, Quicksilver Messenger Service, Bob Dylan, Neil Young, Hendrix, Explosions in the Sky, Mike Bloomfield, Phish, Widespread Panic, The Beatles..Catch-22.

Etc.

Just make sure the music would be something you would normally listen to, that puts you in a good mood, keep the mood mellow while you are tripping.
