Welcome to this digital edition of Phillip Huscher's Program Notes for upcoming concerts by the CSO Feb 21-23. "Triumphant. . . full of power and drama" claimed the Chicago Sun-Times when Riccardo Muti last led the Orchestra and Chorus in Mozart's Requiem. Experience the composer's magnificent final masterpiece as part of a season-long reflection on peace. The first CSO performance of American composer William Schuman's Ninth Symphony, which was inspired by one of Italy's most significant World War II memorial sites, opens the concert.
