The only reason I gave it a 2 instead of 1 was because the opening group, Ben Miller Band, was really fun.
As far as ZZ Top, the sound in the auditorium was awful, you couldn't hear the vocals, and the band had no energy. We've seen them before, and they've done great shows. I don't know if it was an off night,or if the band is tired, or if they are feuding. Dusty and Billy barely came near each other on stage. It was like they were going through the motions, just wanting to get it over with.
If you ever have the chance to see the Ben Miller Band, DO IT! We were a bit skeptical when we saw a washboard and banjo on stage for the opening act, but I have to say, these three guys are so much fun! I'd go see them again, ANYTIME!
