Design critic Philip Nobel reveals his latest crush — on his vacuum cleaner. Kurt Andersen and novelist Emmanuel Dongala talk about artists who were forced to flee their homelands and continue to create here in the U.S., including composers who fled Europe during World War II and found refuge in Hollywood, a profile of the national folk-singing treasure of Albania who left the Balkans for America, and a visit to the studio of Iranian-born filmmaker Shirin Neshat.
