Kurt Andersen and Nathaniel Kahn talk about the physical spaces artists build --- to feed their creativity and to hide from the rest of the world.
Nathaniel Kahn is a playwright and filmmaker. He grew up in Philadelphia, and his father is the renowned architect Louis Kahn. His documentary about Louis Kahn's architecture and his family relationships, My Architect, was nominated for an Academy Award in 2003, and is still in theaters around the country. An avid environmentalist, his other films include My Father's Garden, a portrait of two farmers that aired on the Sundance Channel, and Wilderness: The Last Stand, about the US Forest Service, which was broadcast on PBS.
