Oh my god, I love A Perfect Cricle and I'm heavily getting into NIN. I've only had a chance to listen to The Downward Spiral at this point, but it's already made a huge impact on what I think about music (especially with regards as to the 1990s vs today).
It sucked NIN had to stop touring 2 1/2 years before I start getting into them. They sounded like they put on such a great live show from almost everyone I've heard that had been to their shows.
Cage The Elephant/Foals (5/14)
