With 3.5 million copies sold and chart-topping radio play around the world, Adele’s ‘Rolling in the Deep’ is arguably the song of 2011. You just can’t escape it these days — not even if you’re in the audience for a Linkin Park concert.

At a recent fan club show, band members Chester Bennington and Mike Shinoda unveiled their unplugged version of ‘Rolling in the Deep,’ stripping it down to acoustic guitar and vocals. It offered not only a new take on the song, but a rarely seen side of Linkin Park, a band that has sold more than 50 million units (and won a pair of Grammys) on the strength of its loud, rap-tinged brand of rock.

Linkin Park is currently in the studio with producer Rick Rubin writing songs for its upcoming album, the follow-up to 2001′s gold-certified ‘A Thousand Suns.’ Their ‘Rolling in the Deep’ cover joins previous versions by John Legend and Little Big Town.
