So I just got back from my local music shop and fuck! Usually tehy never have anything, sometimes a few things from Atavistic records. Right now they've got a ton of new used shit. Five Brotzmann(one of which I bought for 18 bucks, worth it), a bunch of Mats Gustafson, Sun Ra, Tim Berne(not really free jazz but what ever) Ken Vandermark and The Vandermark 5. Along with a bunch of stuff I can't remember.
I spent 30 minutes trying to decide which Brotzmann to get, reading the booklets. Some of the stuff is expensive though, the FMP stuff the one I got was the cheapest. Even online though it's big money. Wish I had more than $20 to spend.
Edit:
the one I got
