The best advice I could give you is to NOT start looking into jazz, if you want to play any good music. I mean, if it's to play trash, simply do not play, it will better serve the music.
Kapustin is the best thing you can get if you're looking for printed Jazz music.The 24 Preludes op.53 include some very nice pieces, that are playable at a medium level.
Where is the best place to order these from europe? I keep ending up at the japanese amazon.
Try the album "Sound Grammar" by Ornette Coleman
Indutrial have you seen Jazz on a summers day? I think it featured Eric Dolphy in a band with a cellist and a steel drummer. Do you remember or know what that band was called? It sounded a bit like 70´s psychedelica.
I found the clip on youtube (where else?) Some other good feats in that movie like Jimmy Giuffre.
