Fascinating conversation with renowned music journalist, cultural critic and author Greil Marcus on his new book "The Shape of Things to Come: Prophecy and the American Voice". He has authored many previous books including "Mystery Train: Images of America in Rock 'n' Roll Music" and "Lipstick Traces: A Secret History of the Twentieth Century". In this conversation, Greil discusses "The Shape of Things to Come" and its "kaleidoscopic investigation of American identity" -- he ruminates as only he can about what America actually is -- an idea -- and how this has impacted the country and its idea of itself since its founding to today. An extraordinary discussion with a master writer and storyteller on how he sees America and how America sees itself.
