I like 'em, obviously not everyone's cup of tea, but if you look past the "shouting" vocals, and the quite obvious stereotype that the vocalist "can't sing cos he's crap" (Stone Sour, anyone?) underneath it some of their music and lyrics are quite good. However, their last studio album was, all in all, pants. That live album they released recently I found pretty poor, too.
Stone Sour rules over 'em anyday, but a good band (live and studio) all the same.
