Mozart had achieved rockstar status in Prague, thanks to the adoration bestowed there upon The Marriage of Figaro. He was, therefore, happy to have the nickname “Prague” attached to this symphony at its premiere in that city. It’s a masterpiece, full of sparkling virtuosity, celebration, drama, and humor. The concert opens with the piece that defines the quintessential American Sound: Aaron Copland’s Appalachian Spring, composed originally as the score to Martha Graham’s ballet of the same name.
