Host John Pitman chats with the great Swedish mezzo-soprano, Anne Sofie Von Otter about her performance of a new work by American composer, Caroline Shaw.  Title "Is a Rose", the three-movement song cycle is sung by Von Otter with San Francisco's Philharmonia Baroque Orchestra, as Shaw has written the work with Baroque ensembles - and Ms. Von Otter - in mind.  Next, John talks with the composer herself, touching on the song cycle and her first oratorio, The Listeners, which was inspired by the gold record created for the Voyager spacecraft.  Music from Shaw's new works are interwoven with the conversation.
