Our latest guest on Soundtracking is James Mangold - a returning hero - who joins us to discuss his Bob Dylan biopic, A Complete Unknown. And, as a bonus, we also have a wee chat with Monica Barbaro, who plays Joan Baez in the movie, in what's a simply divine performance. Starring Timothee Chalomet, A Complete Unknown follows Dylan's early success until his notorious and controversial use of electronic instruments at the Newport Folk Festival in 1965.
