Before American composers like Jerome Moross and Elmer Bernstein made the western distinctly their own, the task of scoring the genre fell largely to European émigrés. Hear different perspectives on how the West was won, with music from “They Died with Their Boots On” (Max Steiner), “Gunfight at the O.K. Corral” (Dimitri Tiomkin), “The Furies” (Franz Waxman), “Tribute to a Bad Man” (Miklós Rózsa), and “Once Upon a Time in the West” (Ennio Morricone). Set your pocket watches. The next coach leaves this Saturday at 6 pm.
