Joe Frank: The Known-Unknown

Joe Frank -- the radio producer’s radio producer, the ultimate acquired taste -- passed away earlier this week. He was 79. For over four decades Frank hosted late-night shows that could float between hilarious dreams and suspenseful nightmares, between fact and fiction. And though his shows were rarely mainstream hits, cultural figures like Ira Glass of This American Life and film director Alexander Payne consider Frank a major influence on their own work.

Brooke discusses Joe Frank's life, style and legacy with Jad Abumrad, co-host of WNYC's Radiolab, and Mark Oppenheimer, host of Tablet magazine's Unorthodox podcast, whose latest article in Slate is titled "Joe Frank Signs Off."
