ZZ Top sucks live? You are sorely misguided.
They were the warm-up band for Steve Miller.
Of course, that was 1971...or 2.
I’ve seen them a couple of times including one truly lackluster show at the Tacoma Dome (Washington state).
Can’t blame them (too much) cuz it was the forum (a great big wooden dome structure) that made the acoustics pure crap. Unfortunately they reacted to the acoustics and played very subdued sets. I ws disappointed but it didn’t affect my kinship for the boys...
