Maybe we'll finally know what the heck "ZoSo" is. It Books, an imprint of HarperCollins, has bought a new biography of rock legend Robert Plant, the Led Zeppelin frontman, written by Paul Rees, the former editor of Q and Kerrang! Robert Plant: A Life will be out in the U.K. in October 2013, and released in the U.S in January 2014. Rees interviewed many of the people closest to the singer, and had access to Plant himself. I hope when the interview was over they went into a Guitar Center and played "Stairway to Heaven."
