In the fourth episode of "Barbara London Calling" 2.0, Barbara speaks with Australian artist Tracey Moffat. A true innovator, Tracey began her career as an experimental filmmaker; she has since shown all over the world, including at the Venice Biennale. Her unflinching artwork is a mix of childhood memories, popular culture, history, film, television, literature and dreams, as she uses fiction to comment on her own personal history and on serious issues of social history and the volatile political landscape.
