If there was ever a time I could put the label of “abrasive” on an album, it would have to be for the debut full-length from Disimperium, Grand Insurgence Upon Despotic Altars (Sentient Ruin Laboratories). Take the mystical and obscure portions of black metal, lay them upon the bones of death metal, and crank up the intensity with grindcore and this makes up the uneasy feeling in your gut as you listen to the Oakland natives. Nine tracks at around half an hour is all you need to feel like you got hit by a truck filled with speakers turned up to eleven.
