When I think of Texas, blues rock comes to mind, Stevie Ray Vaughan in particular. In fact, SRV was the King of Texas wasn't he?
I think country music is more of a Nashville thing. Nobody really cares for country music in Texas, come to think if it, not even Southern rock either. Southern rock is more of a Florida thing.
Texas is more of a blues rock state.
Let Nashville guitar players have their twangy country Telecasters, Florida guitarists play southern rock on their Gibsons, and Texas guitarists can play the blues on their Strats. Lol
