Bacewicz’s six-minute Overture for Orchestra, composed during the German occupation of Poland, offers a perpetually shifting palette of colors. Spaniard Joaquin Rodrigo’s animated Concierto de Aranjuez features elaborate orchestration for classical guitar, while Fauré’s tragic Pelléas et Mélisande Suite was originally composed as incidental music for a dramatic play. Borodin’s colorful Symphony No. 2 evokes the exuberance of Russian folk dances.
