Photo by Jared Moossy Watching John Mayer simulate the sounds and antics of fighting bucks is to watch him transform into a rut-addled whitetail himself. He grunts. He snorts and wheezes. He bashes trees with a splintered branch. He paws and grinds the earth. You can almost see his neck swell and his eyes strain with effort and intensity. I have to check to make sure that he hasn't completed his Oscar-worthy performance by urinating down his leg.
