Hard to believe it's been 30 years since Whitesnake released Slip of the Tongue, and to celebrate, the band is putting out an anniversary box set on October 4th. The collection features six CDs containing the remastered record, b-sides, demos, alternate mixes, and even a re-release of the formerly vinyl exclusive Wagging Tongue, where David Coverdale goes in-depth on the album. Also included: a DVD of Whitesnake's 1990 headlining performance at the Monsters of Rock Festival, plus three music videos and a new interview with the frontman and guitarist Adrian Vandenberg. If that wasn't enough, there's a 60-page book filled with memorabilia and a Coverdale signed lithograph snuck inside, which is all available for pre-order on Amazon.
