In my experience anyways, it always seems when you meet a new musician to jam with, or any musician for that matter, and you are talking about bands and influences that ZZ Top is never mentioned unless someone else mentions them first. I find it kind of funny. I would always say ZZ top is one of my favorites and people will say something like "OH YEAH! I forgot about them." It's like they're the band you are not supposed to talk about.
BLUES ROCK ALL THE WAY!
