Metalcore is a metal genre that in its basic form is a fusion of hardcore punk and extreme metal. The name is a portmanteau of heavy metal and hardcore punk. The term took on its current meaning in the mid-1990s, describing bands like Earth Crisis, Funeral for a Friend, Merauder, Deadguy and Integrity. Metalcore is distinguished from other punk metal fusions by its emphasis on breakdowns: slower, intense passages conducive to moshing.
Metalcore is criticized by many people, metalheads in particular, for many reasons, mostly because of what is has become now, mostly "emo" and sing about depressing shit and dressing like girls(just like the glam crap) are just a couple of reasons. so if you ask most metaleads, they will say this is not real metal. which basically means it's not real metal if the entire culture rejects it.
Examples of metalcore bands include Killswitch Engage, Trivium, Shadows Fall, Atreyu, As I Lay Dying, 100 Demons, All That Remains, Avenged Sevenfold, Hatebreed, A Static Lullaby, It Was Burns Red, The Devil Wears Prada and Bullet for My Valentine.Template:Hardcorepunk
