Jimmdavis: After Trace and AM (which both seem to be Uncle Tupelo material), Son Volt and Wilco did not do it for me, so much. I admire Wilco for moving in new directions, while Jay F. seems to be doing the same sort of stuff, but I've tended to sell discs from both groups when I've picked them up.
Have you checked out Two Cow Garage, from Columbus? One of the best rock bands now playing, for my money, and solidly in the No Depression tradition.
And to return to the demised band theme, you might try St. Louis' Nadine, and their very fine "Downtown Saturday."
