Green Day had their moment, although it has passed. The Black Keys are good, but maybe not that mainstream. The best show I've ever seen was Avenged Sevenfold, which is definitely in the metal niche. But I'll never forget when they had a break in the middle of the show, and their lead guitarist came out and just solo'd for a while. Incredible talent.
