When Guns N’ Roses assembled members of their classic lineup in April 2016 for a small club show in Hollywood, they knew it would be a big deal. What they didn’t realize was just how momentous the ensuing reunion tour would be.

Just four years earlier, he shot down the notion of Guns N’ Roses’ classic lineup – also including Slash and Duff McKagan – ever sharing the stage again. Yet, there they were, ready for an undertaking that rock fans had eagerly anticipated for decades.
