Billy Zane: movie star (and secret painter)

Billy Zane reveals that when the cameras stop rolling he rushes off to his makeshift art studio; writer Khaled Hosseini talks about the song by Afghan singer Ahmad Zahir that stopped him in his tracks as a child and still has the power to move him now; Throwing Muses singer Kristin Hersh gives an exclusive performance of a song from her band's new album and talks about her mental illness and how it affected her creativity; in his third Reith Lecture, artist Grayson Perry asks if art has finally lost its power to shock.
