Classical:
Mahler
Ives
Schoenberg
Brahms
Ehhh...more often than not Schubert, but Tchaikovsky takes the spot from time to time (his sixth symphony is such a killer).
Andy Mckee is a fucking legend. I was sitting in my kitchen, listening to The Art of Motion high on hash one time, and it felt like my legs were melting off of me like candlewax. A fond moment I will cherish eternally.
