Kurt Andersen and Oscar-winning composer Rachel Portman pull back the curtains on the usually invisible techniques artists use to make a scene or character or tune more powerful. We’ll visit a master artist who spends her time repainting classic works with the key figures removed. And we’ll learn how bass players are able to switch with ease from staying in the background to stepping in the spotlight. And Aimee Mann stops by the studio to perform and talk about her music.
