Hey guys i was just wondering what specifically is the difference between metal and metalcore? how does one become a metalcore band i mean i can tell the normal difference because metalcore has a distinctive sound but yeah i dont see how what you call the difference?

For example Lamb Of God tour with bands such as As I Lay Dying and Killswitch Engage and they are known for being one of the most famous metalcore bands, yet why isn't Lamb Of God called Metalcore?

Thanks alot.
Lamb of God ARE called Metalcore...

The difference is Metalcore is just Hardcore with metal overtones, or the other way around, if you will. And as we all know, Hardcore =/= metal.

It's an elitist thing.
