Wagner’s Tannhäuser is a musical story of lust, love, and deliverance, as the opera’s title character makes a pilgrimage from the magical realm of Venus to his final redemption in Rome. Strauss’ Ein Heldenleben is an epic portrayal of the hero that exists in all of us, along with the accompanying joys and struggles, depicted through battling brass and tender string melodies. Pianist Pavel Kolesnikov brings his “fluid, fine-toned” (Gramophone) playing to Mozart’s melodic Piano Concerto No. 17.
