But he accomplished his goal, writing a new Bible for American poetry to reflect the democracy and diversity at the heart of this country, and we explore Leaves of Grass in an episode of American Icons. Kurt talks with Linda Ronstadt about being a generation’s most beloved singer, and the disease that made her retire. Plus, we’ll get creative with drones that don’t spy or kill: they dance.
