Guns N' Roses played in Berlin, Germany and tried something they've never tried before – playing a Velvet Revolver song live. Guns N' Roses played Velvet Revolver's 2004 smash hit "Slither" and did a wonderful job with it, though it helps they've got two-fifths of Velvet Revolver on stage with them right now.
For those unaware, Velvet Revolver's lineup includes guitarist Slash and bassist Duff McKagan, as well as ex-Guns N' Roses drummer Matt Sorum who is not part of the reunion, Stone Temple Pilots frontman Scott Weiland who passed on in 2015, and guitarist Dave Kushner.
