i like circle takes the square, number twelve looks like you, a day to remember, emmure, devil wears prada, sleeping with sirens, atreyu, strung out, snot, broadway, and many more.
those are pretty much my favorite metalcore/screamo bands
honestly, i havent heard of most of them :P i will have to look them up. but i love atreyu! and a day to remember and devil wears prada. they are amazing.
circle takes the square isnt around anymore, the number twelve looks like you also broke up about a year ago, emmure just came out with a new album here earlier in 2011 which is really good, sleeping with sirens as well, and i havent heard of anything from snot and strung out in a long time
