I just made it back home from the concert! (I know it was two days ago, don't judge.) I have seen them several times now. If you get a chance to see NIN live, treat yourself and do it. They always put on a great show. I think I may have overdone it on the floor, however. I have bruises in weird places, and it hurts to lift my arms above my head. Not to mention I am still hoarse. I don't even care, I would do it all over again in a heartbeat.
