Welcome to this digital edition of Phillip Huscher's Program Notes for upcoming concerts by the CSO Nov 27-29. Marin Alsop, "a shooting star in the firmament of international conductors" (Penguin Guide to Compact Discs), conducts a program of absorbing masterworks. Barber's noble Second Essay for Orchestra, written during World War II, prefaces Gershwin's exuberant Rhapsody in Blue, featuring Jon Kimura Parker, an enormously versatile pianist who has a long history with the popular piece. Dvorak's glorious and emotional Symphony No. 7 closes the program.
