Some exotic and ancient music is today’s highlight of beautiful music. Jordi Savall and Hesperion XXI perform their LACHRIMAE CARAVAGGIO (Caravaggio’s Tears) program of improvisations on the works of the artist Caravaggio. The featured performers include Mr. Savall on viola da gamba, with violinists Riccardo Minasi and Xavier Puertas, and harpist Andrew Lawrence-King. The music is achingly otherworldly.
