Antonín Dvořák’s eighth symphony is often described as cheery, genial, and upbeat. It offers one delightful melody after another, whether evoking themes from Bohemian folk music the composer adored or scenes of local pastoral beauty. As one conductor instructed the orchestra before the fanfare that opens the fourth movement: “Gentlemen, in Bohemia the trumpets never call to battle—they always call to the dance!” Speaking of fanfare, this concert opens with Mason Bates’s Soundcheck in C Major, which is, in his words, “a fanfare animated by sonic effects” that might remind some of Wagner, and others of Pink Floyd.
