S1, E2: The normally guarded Lou Reed - widely regarded since his Velvet Underground days as music's Prince of Darkness - opens up with Elvis Costello, revealing himself to be a witty and literate raconteur. He speaks movingly, and funnily, about his love of R&B, New York, art and the mysteries of writing and creativity. Lou's close friend and collaborator (on the film "Berlin"), Julian Schnabel, joins the fray mid-show, to both heartbreaking and hilarious effect, contributing some disarmingly candid and personal remarks, as well as a riveting - and totally spontaneous - spoken-word performance. Lou breaks down one of his classic compositions on guitar, and then joins Elvis for two amazing performances.
