Heavy Metal Sunday is not safe for work. Or children. Or pretty much anything.

The theatrical, absurdist Swedish metal band Ghost B.C., previously known as just plain Ghost, are the latest band to find international fame by scaring the hell out of parents and authority figures, dressing up as cult members and demon-priests and plying an infernally catchy form of craftsmanship.The band is getting ready to unleash the sophomore album Infestissumam upon the planet. Below, we’ve got the super-NSFW video for their song “Year Zero.” It’s gleefully Satanic silliness about a coven of witches who welcome a dark stranger into their midst. Nudity abounds. Don't say I didn't warn you.
