The Rolling Stones have endured more than fifty years of a rockstar lifestyle, touring the world countless times and swapping out their blood (toxins) to keep going.

Their latest move is a reissue of their 1971 classic Sticky Fingers, an album that included classics like “Brown Sugar,” “Moonlight Mile,” and “Wild Horses.” They’re releasing alternate cuts off the album too, and today the band unearthed an unheard version of that Guitar Hero classic, “Can’t You Hear Me Knocking.”

It’s a shorter, smoother cut than the virtuosic take that ended up on the album. Stream above, and look out for the Sticky Fingers reissue in the coming months.
