Welcome to this digital edition of Phillip Huscher's Program Notes for upcoming concerts by the CSO May 3-5. Semyon Bychkov returns to conduct Tchaikovsky's vividly dramatic Manfred Symphony, based on Lord Byron's tragic and enigmatic hero. The legendary Labeque sisters, "the best piano duet in front of an audience today" (The New York Times), join the CSO for a rarely performed gem, Bruch's richly melodic Concerto for Two Pianos.
