Apparently notable rock bands – including Pearl Jam, R.E.M. and others – have asked the Department of Defense to reveal what songs were used during interrogation of detainees at U.S. prisons, including the Guantanamo Bay detention facility.

In a reaction posted on the campaign’s website, CloseGitmoNow.org, R.E.M. described the unpermitted use of their friends’ music to torture detainees as horrific.
