I've only caught them at the club once (09).
The 2nd Black Pus set there when he opened for ratatat was the funniest loud show experience. The front row consisted of myself (wanted a good spot for Black Pus) and HS kids probably at their first show. Needless to say, they were not equipped with the proper ear protection. Chippendale comes out and hits something that causes some of the highest shards of feedback I ever heard to ring out throughout the room. I turned to one of the kids and said "oh yeah...you may have wanted to bring earplugs." Chippendale then proceeds to do irreparable damage to their hearing for 30 minutes almost non-stop. As agonizing as it must have been, they did stand there and take it.
That Ratatat set was unnecessarily loud as well. And it sucked. I think I left 15 minutes in.
