An Iranian century of music

Iranian music is inescapably political. Since the Islamic Revolution in 1979, music there has been subject to heavy censorship by the government. Before then, musical expression ebbed and flowed alongside a social and political landscape that was in constant motion. How Iran's music tells the history of the country from the early 20th century to today is the subject of a new book, "Iran Amplified: One Hundred Years of Music and Society." Co-editor Nahid Siamdoust joins Host Marco Werman to talk about that history.
