When the Chieftains' intrepid bandleader, Paddy Moloney, first heard Carlos Núñez, a young recorder and bagpipe virtuoso from a far-flung Celtic outpost in Spanish Galicia, he was mightily intrigued. Santiago explores a tradition that draws on medieval, Spanish, and Celtic sources; the music is performed on instruments that have changed little over the centuries. Núñez represents the home team, while Los Lobos and Linda Ronstadt personify its Central and South American descendants. Elliot Fisk, a pupil of the guitar maestro Andrés Segovia, and Ry Cooder respectfully contribute sparkling riffs. "Dublin in Vigo," a live track with joyous playing and a high-spirited ambiance, is merely one highlight of many. --Christina Roden
