ZZ Top

ZZ Top built their name on a heavy blues rock foundation, with songs like "La Grange," "Sharp Dressed Man," and "Gimme All Your Lovin'" turning them into classic rock radio staples for decades. The Texas trio's mix of grit and humor, plus those long beards, made them one of the most recognizable acts to come out of the southern rock scene.

They've got a show coming up in Colorado at Pikes Peak Center.
