A list of metalcore bands, more or less.
I listen to quite a few of the bands listed, such as 36 crazyfists, The Agony Scene, All that Remains, As I Lay Dying, Atreyu (old Atreyu, not their new shit), Black Dahlia Murder, Bleed the Sky, Bleeding Through, Caliban, Everytime I Die, God Forbid, Heaven Shall Burn, Himsa, Killswitch Engage, Lamb of God, Misery Signal, Poison the Well, Shadows Fall, Sinai Beach, Still Remains, Threat Signal, Trivium, Unearth...
That took too long, I'm not all about categorizing metal, I like a good variety personally. But I suppose a lot tend to fit into the metalcore category.
