Principal Guest Conductor Markus Stenz gives us a rare opportunity to hear the color and brilliance of Stravinsky’s complete score for The Firebird, the commission from Diaghilev’s Ballet Russes that catapulted him to fame in pre-WWI Paris. Years later, Paris was again the setting for Ravel’s popular jazz-inflected concerto, a perfect vehicle for the musical refinement and elegance of French pianist David Fray, who makes his BSO debut.
