Back in 1978 and 1979, art collector and socialite Peggy Guggenheim gave what would become her last interview. She spoke to Jacqueline B. Weld for her biography, Peggy: The Wayward Guggenheim. Those tapes were thought to be lost before director Lisa Immordino Vreeland (Diana Vreeland: The Eye Has to Travel) found them as she was working on Peggy Guggenheim: Art Addict, her fascinating documentary about the woman. Those never-before-heard tapes form the main narrative structure for this well-crafted warts-and-all documentary that shows at 7 tonight and at 7 on Friday night at the Cleveland Museum of Art. Tickets are $9. (Niesel)
