Well it appears I have held a very different idea to what Metalcore is to most of you people. Me (and most of the people I know who are into heavy music) have always considered it to be quite a distinct style, taking certain elements of the hardcore and death/thrash metal genres. Some of these elements would include the dry-crunch distortion found in hardcore, many odd-time signitures and wild tempo changes, blastbeats, hardcore-styled breakdowns, often technical playing by the instrumentalists, use of both the death metal roar and hardcore scream/yell, among other things. Bands who use this would include The Red Chord, Between the Buried and Me, 7 Angels 7 Plagues and Cephalic Carnage to name a few. The wierd thing is that most of the people I know have the same idea about Metalcore as me and if you tried to tell them that Killswitch Engage is a Metalcore band, they'd probably think you're completely nuts. It also appears that Metalcore is pretty open to interpretation...cuz I've said it already but I honestly dont see how anyone could possibly see any similarity between BTBAM and Killswitch. I guess now I'm not so baffled at why most people here seem to be very Anti-Metalcore haha.
