Musical Book of Hours
This is one of the most beautiful early music discs in the catalog--equally attributable to  the music and to the perfectly tuned and blended voices, whose timbres couldn't be more appealing  to the ear or more appropriate to the style of the repertoire. The very first track--a charming, gentle,  hopeful little piece by Dufay, "Bon jour, bon mois, bon an"--leads us easily into the  heart and spirit of this well-conceived program, which seeks to duplicate in music the expressive  power and visual beauty of the richly illustratedBooks of Hours--lovingly created volumes  that were a cherished fixture of religious devotional practice in medieval and Renaissance Europe.  Among the composers represented are Dufay, Desprez, Busnoys, Dunstaple, and Ockeghem. Put  this at the top of your list.--David Vernier
