A sub-genre that does not exist but will soon when the scene kids are finished ruining Death Metal with Deathcore. It will be a mix of metalcore and black metal. It will sound like Immortal fused with Bullet For My Valentine. Common features of blackcore will be breakdowns every ten seconds and high pitched pig sequels. The bands will probably wear some thick eyeliner and black lipstick, some weird looking tattoos and piercings everywhere on their faces. The bands will NOT wear corpse paint as well. To summarize this is the scene version of Black Metal and we should do our best to stop the infection of metalcore.
Remember kids...say no to metalcore!
Scene Kid: Oh my god man have you heard this br00tal blackcore?
Metalhead: What hell is that?
Scene Kid: The most br00tal thing next to deathcore. It's like the popular and cool version of Black Metal. Its metalcore fused with black metal.
Metalhead: *Sighs and walks away*.
