Legendary rock guitarist Slash recently joined Aussie rock quartet Wolfmother on stage in front of a sold-out crowd at Los Angeles’ Wiltern Theater for an epic rendition of “By The Sword.” The track, which came together as a collaboration between Slash and  Wolfmother front man Andrew Stockdale, will be featured on Slash’s forthcoming solo album. In a fan captured video both the band and crowd rock out while Slash gives the audience a flawless guitar solo.
