Richard Proulx and the Cathedral Singers present this first volume in a historic series of choral masterworks from the 15th to the 18th centuries. Faithful to the original compositions, it includes works by Byrd, Montiverdi, Dufay and others, including Exsultate Justi, Ave Maria, Ave Verum Corpus, All Glory, Laud and Honor, O Esca Viatorum, and 13 more.
