mofimadness, you might check out Amanda Pearcy, another Texas (Austin) singer/songwriter. Her second release, "Royal Street," is the best place to start IMO.
Lee Ann Womack
I happened to see a story about her newest disc (The lonely, the lonesome & the gone), took a chance, and it's become one of my favorite discs, often on repeat. I realize most know her from one cross-over hit (I was in that group-and an old friend of mine co-wrote that one) but there is a LOT more to her than that song. This is a great great recording with great songs, if you like and appreciate this type of east-Texas "classic" country. If you do, this is well worth a listen.
