If your name's "Pepper Keenan," you run a cheerleader camp, right? If your name's "Woody Weatherman," you're a cartoon meteorologist on "SpongeBob SquarePants," right? And "Reed Mullin" and "Mike Dean" are the guys whose high school debate team went to regionals before losing to those darn IQ champs at Choate.

These four innocuously-named guys in fact comprise the North Carolina band Corrosion of Conformity. They intently mix beakers of grunge, punk and metal into a sound that happily reminds fans, in synesthesian fashion, of the gray-black sludge you'd find seeping out from under a bandage on the swollen leg of an abandoned infantryman at Gettysburg.

If that's not descriptive enough for you, maybe you can get a good idea of the Corrosion of Conformity sound by the cover art their latest album, "No Cross No Crown." It  depicts a little girl standing at Stonehenge, holding a human skull yearningly towards the twilit sky. You go, young lady, and seek those dark gods!

See Pepper and Woody and Mike and Reed when they bring the rock Friday in a free show at the Mohegan Sun Wolf Den. 

Corrosion of Conformity, 8 p.m., Mohegan Sun Wolf Den; free.
