If you saw Amadeus, you probably remember its portrayal of Mozart on his deathbed, sweating over the Requiem while his plotting nemesis Salieri takes dictation. Sorry, yallthat compelling story draws as much from a play by Pushkin as from history, but Mozart really did leave the great work unfinished at his death in 1791. The Requiem has traditionally been played as it was completed by some of Mozarts pupils, but for the NSOs performance conductor Giancarlo Guerrero has chosen Robert Levins 1993 version, which aims to bring these completions closer to what Mozart might actually have written had he lived. The program also features Arvo Pärt's meditative 1977 Cantus in Memory of Benjamin Britten and Witold Lutosławski's Bartok-influenced 1954 Concerto for Orchestra. Tickets are $35-105.
