a lot of Coltrane and Miles, but most of all Anthony Braxton. The Iridium box set (still struggling with that one; I may never make it all the way through!), the duet with Joe Fonda that was reissued on Clean Feed (from 1995, I believe), the GTM Six Compositions box, and I've been exploring the Hatology label with the Jazz Loft's periodic sales.
As for non-jazz, I've been really enjoying the latest Neil Young Chrome Dreams II, Ryan Adams, Jay Farrar's solo catalog, and Son Volt
