Italy's Firenze Festival felt the heat from a rockin' collaboration on Thursday (June 14).   

The Foo Fighters surprised fans during their set by bringing out Axl Rose, Slash, and Duff McKagan for an epic performance of Guns N' Roses' 1987 hit, "It's So Easy." The rockers ran about the stage for a wildly dynamic delivery.     

GNR will be hitting the festival stage on Friday, in the midst of the international leg of their Not In This Lifetime Tour. Watch a clip from the collab below, via a fan from the audience.
