My guitar instructor is like seventy years old now and still holds concerts. The man rocks so fucking hard.
My first "concert" was going to his benefit show raising money for the Harley Davidson biker's club chapter of my town. Since he and I are friends, I got in for free, got free beer (all I could drink!) and got to basically do whatever the fuck I wanted. He played a few kickass old songs (a few that he wrote, which are all catchy blues songs, and some covers) and then decided to go all the way to white-trash town and played Freebird.
Halfway through the solo, his (also incredibly old) keyboardist started yelling profanities - apparently caught up in the huge keyboard solo - and my instructor accidentally knocked over an amp. Seeing a seventy-ish year old Vietnam vet rocking the fucking house, kicking amps and yelling "YEAH! YEAH! GO BERNIE GO!" is possibly the coolest thing I've ever seen.
So my first concert wasn't exactly a concert, but it still kicked more ass than anything else I've ever gone to see live. Even CKY.
They fucking sucked.
EDIT: Hail the Villain opened for CKY, however, and they were absolutely awesome. The lead singer was so energetic it was impossible not to enjoy yourself (he was pelvic-thrusting at the bassist's face in time with the crash cymbals).
