Mojo: You ought to check Wilco out. They defy categorization. Some stuff sounds like 1970s mid-tempo rock, then they have all-out country stuff that the Stones would have been proud to record in the Let it Bleed and Goats Head Soup era, then they have stuff that is post-alternative that just goes into their own realm. Great musicianship, songwriting, etc.
I'll check 'em out on I Tunes a little later and get back to you.
Wilco rules and I'm a big Uncle Tupelo fan, but I can't write off Jay Farrar. I have all 3 Son Volt albums, and I think they're great albums. The Mermaid Avenue albums are excellent. Jay Bennett is a freakin bozo, but damn he is a great musician and an awesome songwriter.
