Nine Inch Nails. It was good, no where as good as Lights in the Sky, but still a good show with some surprisingly good song choices (Even Deeper?! Holy shit!), but there were alot of baseball cap wearing douche bags there as well for some reason.
What show did you go to? I watched a full recording of one of the shows, and while it was cool, LITS blew it away. I would have liked to hear some of the different songs he's playing though like Even Deeper, All the Love in the World and Into the Void. I'm not a fan of the backup singers, if he does a 2nd leg (come to Philly!) I hope he leaves them at home.
