Story : Season 12 of Great Performances at the Met continues on PBS on Sunday, March 25, with the American premiere of Thomas Adès’s The Exterminating Angel, a surreal fantasy about a dinner party from which the guests can’t escape. The Exterminating Angel was inspired by the classic Luis Buñuel film of the same name, and stars John Tomlinson and Alice Coote. Mezzo-soprano Susan Graham is the host.
