Welcome to this digital edition of Phillip Huscher's Program Notes for upcoming concerts by the CSO Mar 9-11. Stravinsky's ballet about the lovelorn puppet Petrushka remains one of the most striking orchestral works of the modern repertoire. Esa-Pekka Salonen couples Petrushka with John Adams' equally playful Slonimsky's Earbox and the world premiere of Salonen's own Cello Concerto, played by the legendary Yo-Yo Ma.
