By now we’re all familiar with the U.S. government’s practice of using heavy metal to torture detainees. We’ve all seen “Zero Dark Thirty” and “Homeland”—we get the drill. Usually metal music is used for its general unpleasantness. It’s impossible to sleep through and just all-around unnerving.

Except Canadian band Skinny Puppy had no idea their music was being used in the service of the U.S. military.

While Skinny Puppy aren’t exactly metal they are pretty freaky. Freakier than anything that has any business coming from Canada, really. Their live shows feature costumes that look like this:

And fake maiming, like so:

So I guess they actually make a pretty logical choice when picking out music with which to torture someone.
The Independent points out Friday that when Metallica learned their music was being used as a torture device at Guantanamo they sent the the government a cease and desist. Skinny Puppy, on the other hand, went the other way and just sent an invoice.

“We heard that our music was used on at least four occasions,” Evin Key said. “So we thought it would be a good idea to make an invoice to the U.S. government for musical services.”

Asked how he felt about his music being used to torture people, he said, “Not too good. We never supported those types of scenarios. Because we make unsettling music, we can see it being used in a weird way. But it doesn’t sit right with us.”

The band has decided to name their next record “Weapons” in apparent protest. I wouldn’t hold my breath on that royalty check, though.

In related news, President Obama promised to close down Guantanamo Bay this year in his State of the Union address, six years after promising the same when he was first elected.
