Ahh, an As I Lay Dying fan, huh? You might like some of this stuff then...
SkyCameFalling (best band ever), InDyingDays, Atreyu (old stuff, fucking sellouts - I was close with the lead singer when they played small venues back here on LI - now, pfffftttt), Zao (yeah, go Christian metalcore), Alove For Enemies, Nothingface, Mudvayne, Hopesfall (great melodic metalcore), Every Time I Die, Anterrabe (I'm picky here, but their name sounds cool), DownTheSun, Dillinger Escape Plan, Converge, Curlupanddie (Vegas represent, word), Comeback Kid (kinda happy, not metalcore but it's fun - beware though, it's Canadian), and Caliban.
Christ there are more than I thought.
