Hardcore punk:

:sweat: HOO BOY.

After Hardcore punk got it’s feet on the ground, many of the originators in the DC area spun off to make what was refered to Emotional Hardcore, shortened to Emo. At the same time, bands were pushing the limits, this i’m less knowledgeable about, creating the basis for power violence. Also Bad Brains, they were important.

Elsewhere metal influences started to appear, and that was referred to as just Cross Over. That would influence the sound of other bands, mostly in the northeast to become Metalcore, there would also be a slowing down of songs, creating Beatdown Hardcore.

Power violence somehow got mixed back with Emo to create Emo Violence, this would be often referred to as screamo. Then to skramz for the kids who didnt like the wave of Post-Hardcore bands that got a little screamy and about as misogynist as per usual despite hardcore starting from rather revolutionary roots, being called screamo.

Meanwhile it was still being called Hardcore, all of these names are retroactive.
