"Despite what Atreyu may think, the roots of metalcore go back to the late ’80s and it was a fully formed genre by the early-to-mid ’90s, way before the mainstream metalcore boom of the early 2000s that put a lot of the genre’s overly-polished bands on MTV. Like a lot of underground genres of music that suddenly hit it big, metalcore had some growing pains, but recent years have seen the genre’s influence being reinterpreted by great newer bands who — going by their age — presumably found metalcore from the bands on MTV and then traced its roots back to the underground bands of the ’90s."
