What It Is To Burn is one of those albums that tests just how important nostalgia is to its listener. If you had a deep connection with it when the album first came out, chances are you'll love it. If you liked it, but weren't exactly enthralled with it, chances are you'll think it has aged horribly. I happen to be in that latter camp. When I was 15 this was great. Now at 26 it's nothing more than slightly less annoying bro-rock. It's not without its moments, but you might want to stick with how you remember it sounding rather than taking the time to give it another spin with an older set of ears.
Pop punk and post-hardcore working together. Nothing here is really new, but it's just such a fun and upbeat album to listen to, with surprising depth in a couple of the songs (Project Mayhem for instance).
