The artwork for many pornogrind albums is noted for its over-the-top extreme graphically sexual content and is sure to piss off your parents. Notable bands include Gut, Cock and Ball Torture, and Waco Jesus (nothing offensive to see here).
Also known as scrunk, this genre combines uptempo Southern hip hop influences with screamo.

Notable bands include Brokencyde, Hollywood Undead and Blood On The Dance Floor.
