The show was awesome. They definitely had the amps turned to 11 though, my ears are still ringing. The set seemed short, but I think it was just my perception of things – if it were up to me, they’d still be playing.
for what it’s worth, there were tons of people videotaping the show in Atlanta at the Variety Playhouse, and I didn’t notice anybody getting hassled. I guess it probably varies by venue though…
