Tune in Sunday at 2 pm to hear Spanish conductor Pablo Heras-Casado makes his Chicago Symphony debut in music of Debussy, Ravel - and his countryman, Falla, performed with a flamenco singer from Spain. After Ravel's "Tombeau de Couperin" and "Pavane for a Dead Princess" and Debussy's ballet "The Toy Box," Heras-Casado and the CSO are joined by cantaora Marina Heredia for Falla's "Love, the Magician."
