At this point I feel nothing is out place in my library, its all music. What were once sore thumbs have become my cornerstones. But when being introduced to it, it was all about the context I came into contact with it and associations to things I already actively enjoyed and embraced.

Igor Stravinsky - Was in band in high school college and a favorite of The Flaming Lips
Erick Satie - Influence, and often compared to the great Jon Brion, my favorite film composer
Miles Davis - Bitches Brew was a favorite of The Mars Volta, On The Corner of the Roots. and most of all, my friends all loved him. and come on, its fucking MILES!
Wu Tang Clan - It became the cool ironic thing a couple years ago, but i actually got into it
Blink 182 - I don't listen to much pop punk these days, but these guys started me on my musical journey.
Satyajit Ray - The Darjeeling Limited
