These early records from four sextetos range from the illustrious Nacional and Boloña to the equally fine but less known Matancero (led by the great Isaac Oviedo), and Occidente -- a rarity in that one of its lead singers was a woman. All are prime, though Occidente is a little weaker than the rest, but more important all have the tart and delicate drive of one of the classic 20th-century sounds.
