The Rolling Stones are at Empower Field in Denver Thursday night for one of just 16 stops on a North American tour, and they are delighting local fans before ever taking the stage. One day before the event, the legendary rock band unveiled what appears to be a concert poster featuring one of the Mile High City’s own wild, wild horses, “Mustang.” Or as you colloquially know him, Blucifer. In the graphic, the local icon sports his signature red eyes as well as the Stones’ classic tongue and lips logo.
