Elijah Wald, musician, writer, historian, and author of “Dylan Goes Electric! Dylan, Seeger, Newport, and the Night that Split the Sixties,” the book that inspired “A Complete Unknown,” joins John Williams to talk about how his book differs from the movie, how the first scene in the movie impacted him and how it made it easier to watch the film, what the film gets wrong about some of the characters and events, how controversial it was when Dylan ‘went electric,’ how political Dylan actually was, and how he enjoyed Timothée Chalamet’s performance and the movie in general.
