This episode of The Gravy takes an in-depth look at art in prisons. Host Warren Maxwell interviews inmates who have embraced painting or carving while serving time in Mt Eden, Paremoremo and Rimutaka prisons. At Rimutaka, art tutor Paul Bradley points out that art is a vehicle for change both for prisoners and the art audience, and former prisoners talk about how art has changed their lives for the better. Outside the walls, Warren visits at a caged exhibit of musical instruments at Artspace in Auckland and plays a few bars on the flute.
