ps. it's sean!
Bitches Brew is up there, Jazz in general is really great, The Dark Side of the Moon "...is all your life will ever be." talk about existential pop music, woah! Jethro Tull, Hendrix, Coltrane(s), Sabbath I & II, etc... much more. The good sound from the 1960s and 70s psychedelic/ eastern- turkish-indian-gypsy-/ free yazz/ jazz/ funky/ bluesy/ space rock and everything in between. all of it.
I live parts of my life in fantasies inspired by Jean-Pierre Jeunet's beautifully surreal art of film. It's inevitable; the man is genius. Woody Allen is really great too.
absurdism, french existentialism in general is usually pretty nice, subjective reality & and the whole free will scheme, Camus, Sartre, Dostoyevsky is really great too, and Nietzsche.
"How do you escape the absurdity of your existence, with hope, or with suicide?"
