Deep Ellum in Dallas is also good for blues and is much different then the blues that you would get from Austin and the blues that is played in Deep Ellum is the true Texas blues and Austin blues is more like Chicago style blues. In Deep Ellum you'll hear more slide guitar like you would from Beale Street, but in Austin they use alot of electric guitar(which is what Stevie Ray Vaughn is known for, even though he is not as true Texas blues singer compared to his brother Jimmie Vaughn). In case you didn't guess I'm a big blues fan, particularly of true Texas blues(Blind Willie Johnson is my favorite, but that's going way back in the years).
