I'm just now listening to music by Joe Ely, and it occurred to me that his music might be called country rock. Or maybe Roots Rock with a healthy dollop of country.
I've only discovered his music in the last few years, but I've enjoyed everything I've heard so far -- particularly his early solo stuff from the late-70s & early-80s.
Ely is from Amarillo, and -- along with Jimmy Dale Gilmore & Butch Hancock -- he was a founding member of The Flatlanders. He definitely came out of the Texas "progressive country" scene that blended country, folk, and rock in interesting ways.
Anyhow. Ely's well worth a listen, IMO.
