Rage Against The Machine, Pearl Jam and Nine Inch Nails have joined other musicians including REM and Billy Bragg to support US president Barack Obama’s campaign to close Guantanamo Bay prison.Guantanamo Bay prison is a detainment facility located in Cuba where the US military are allowed to indefinitely detain any non-US citizen who is believed to be involved in terrorism.Rage Against The Machine guitarist Tom Morello said: "Guantanamo may be [former US vice president] Dick Cheney's idea of America, but it's not mine. The fact that music I helped create was used in crimes against humanity sickens me - we need to end torture and close Guantanamo now."Under the banner of The National Campaign To Close Guantanamo, the musicians are lobbying the US’s National Security Archive in Washington under the Freedom of Information Act to request to see classified records that detail the use of loud music as "an interrogation device".According to the National Security Archive, terror suspects have been tortured with songs by Rage Against The Machine, Britney Spears, the theme tune to Sesame Street, Barney The Dinosaur’s title song and a number of tracks by shock rocker Marilyn Manson.The CIA insist that if music was played at Guantanamo, it was played at “levels far below a live rock band".
