We're hearing recent recordings by two US-based ensembles on this week's show. Hymns of Kassiani from Cappella Romana features the world's earliest music by a female composer: the 9th century nun, poet, and hymn writer Kassia. We'll also hear from El Mundo, directed by Richard Savino. They're presenting music from the archive of Guatemala City Cathedral.
