I've seen them live quite a few times now and even though I wouldn't call them terrible I know what the kids talking about.
I just feels like their live performances don't have the wall of sound that their albums have. Still great band though.
to the dipshit talking shit on their live show: that wasnt their fault. the guitarist was using borrowed equiptment that kept fucking up. and that place sound like my ass anyway. ive seen this band live many a time and trust me, they fucking rule. dont let one bad experience ruin it for you. go see them again and you wont be dissapointed. trust me.
