The incomparable American soprano Renée Fleming returns to Symphony Hall to join Andris Nelsons and the BSO in the gorgeous and touching final scene from Richard Strauss's "conversation piece for music," the opera "Capriccio". The opera's opening Sextet for Strings and luminous Moonlight Music will precede the vocal scene. On the second half is the composer's "Also sprach Zarathustra", his tone poem based on the German philosopher Friedrich Nietzsche's mystical meditation of the same name. The piece opens with a dramatic fanfare (widely known from its use by Stanley Kubrick in the sound track of "2001: A Space Odyssey"), perhaps the most famous "sunrise" in music.
