Owl , I have got to see zzTop 3 times. First time was on their xxx tour. Was the most awesome thing I have seen so far. During blue Jean blues, Billy fell all the way back on his back picking the guitar.
First time I saw them was in 1977 - Been a fan every since. Probably seen them 10-15 times. I like just about everything (except there so called "Disco" era).
