I just saw the show in NYC last night at Hammerstein, Franz Ferdinand absolutely blew Death Cab out of the water. I've seen them both before, and I don't think I'll pay to see Death Cab again until they release another spectacular album (which judging by Plans could be awhile). And I've been waiting for Franz to come back since their 9:30 show (summer 2004?), and had remembered them being so fun live. It was no contest.
NYC crowds proved to be just as chatty as D.C. crowds last night, but I think a lot of that had to do with their different fan bases. I can't imagine what it would have been like to see Death Cab after Franz like they did in D.C., the vibe would have been wicked off.
