The Mayhem Festival hosted an afternoon at Whisky A Go Go on Monday to promote their upcoming U.S. tour. Metal fans witnessed an epic motorcycle processional down Sunset Boulevard escorted by the Hell's Angels, a red carpet arrival and press conference. Acts from the tour in attendance included Rob Zombie, Five Finger Death Punch, Butcher Babies and Huntress, among others. To complete the event, Huntress and Butcher Babies took to the stage and blew the roof off the place. What a way to spend a dreary Monday in Los Angeles. All photos by Hannah Verbeuren.
