Eljr, for smart, innovative jazz, I would also recommend a small, collectively-owned label out of Frisco (I think) -- Cryptogramophone. Guitarist Nels Cline, who has been a member of Wilco for several years, is almost their "house" guitarist and has five or six releases on the label. I like everything he does -- and I don't think I've ever heard a bad Cryptogramophone release.
Another really smart, adventurous label is the British Discus label. The releases are all over the place and some are truly avant garde, so you should just check out their Website (likewise with Cryptogramophone). In particular, listen to some clips from "Orchestra of the Upper Atmosphere" or "Combat Astronomy." Amazing stuff, in my estimation
Cheers,
Bill
