definitely. Also Uncle Tupelo and Son Volt.
Truck Stop Love (from Manhattan, KS), Split Lip Rayfield (from Wichita, KS), and Frontier Trust (from Omaha, NE) were favorites in this regard as well. Grew up around this scene and was fond of it, and some of that music still holds up.
less rock, more country, and beautiful at that: Freakwater.
I guess I don't really need to get into the Byrds, David Crosby, or the Dead, but... it's there if you want it. Ditto GP, Burritos, and International Submarine Band (great).
