Skinny Puppy says its music used for torture at Guantanamo

Canadian electro-industrial music genre pioneers, Skinny Puppy, recently found out their music was used to torture detainees at Guantanamo Bay, so they've decided to send a bill.

A former Gitmo guard, who is writing a book on his experiences, says that inmates were exposed to bootleg recordings of the band's music, at incredibly high volumes, for up to 12 hours at a time. Often until the detainees soiled themselves.

Skinny Puppy founding member, cEvin Key, says the band is sending the U.S. Department of Defense an invoice for $666,000 for its use of their music. Members are also considering a lawsuit against the department.
