Based on who you have said that you like, I would suggest that you pick up "The Yellow Shark" by Frank Zappa, as well as "LSO - Zappa". I think you would really like it, if you also like Danny Elfman who was surely influenced by this music. Then, I would check out Bela Bartok, Edgar Varese, and Igor Stravinsky, whose music influenced Zappa. Bartok's Concerto for Orchestra is a necessity in any serious music collection, and I highly recommend it.
Cheers.
