Gnarls Barkley has released their latest release The Odd Couple in its backwards form, appropriately titled elpuoC ddO ehT, in its entirety for free. Why? We're not quite sure either, but Danger Mouse has a track record of releasing his projects in reverse before. His Grey Album, an unlikely mash-up of The Beatles' The White Album and Jay-Z's The Black Album, featured "Lucifer 9," which revealed lyrics that purportedly sound as if Jay-Z is saying "Murder Jesus 666." Upon first listen to elpuoC ddO ehT it's actually quite listenable, and there's thankfully no hidden Satanic messages coming from the Gnarls Barkley duo. You can download your copy here.
