Amazon.comThis beautifully packaged disc couldn't be more esoteric in theme--but that doesn't mean that its contents won't appeal to a wide range of listeners. If you love medieval vocal music, you'll be fascinated by this unusual collection of mass movements written by two Italian composers-- Matteo and Zaccara--that are juxtaposed and organized both to contrast their styles and to make programmatic sense. There's lots of fancy ornamentation and there are many dramatic moments, as well as sections of sweet, gentle lyricism--listen to Matteo's "Gloria," sung with heart- rending tenderness by soprano Jill Feldman. The singers are alternately accompanied by recorder, harp, fiddle, bells, and organ. This is a remarkable addition to the early music catalog that compels serious listening. --David Vernier
