Thirteen of the 28 tracks on this broad survey of El Siglo de Oro feature the voice of Guillemette Laurens, familiar from other early-music ensembles, typically alternating with the instrumental works. She is accompanied on organ, harp, vihuela, and percussion, the organ an instrument at Lorris-en-Gâtinais dating to 1501, rebuilt a century later, and restored in 1974. The disc takes its title from an anonymous song that comes, like the rest of the program, from 16th-century Spain. The cover art is El Greco’s only portrait of a woman, currently located in Glasgow.
