A Canadian hard-rock band says it has sent the Pentagon a bill for US$666,000 ($802,000) after a former Guantanamo Bay guard alleged that the US military used their music to torture detainees.
Skinny Puppy found their music was blasted out at the detention centre in southern Cuba from a former guard who is a fan of the band, keyboardist Cevin Key told Canada's CTV Television.
Rights groups say that prison officials subjected Guantanamo's terror suspects to "deafening loud music", often featuring violent lyrics, during interrogations.
Several other bands, including REM, Rage Against the Machine and Metallica, have denounced the use of their music at Guantanamo.
"We sent them an invoice for our musical services considering they had gone ahead and used our music without our knowledge and used it as an actual weapon against somebody," Key told CTV. The amount they requested may be a reference to 666, known as "the devil's number", in light of the band's Gothic themes.
