In his day a much-admired composer, the Burgundian Antoine Busnois has been eclipsed by his great contemporary Jean Ockeghem. Best known today for his elegant songs, his church music reveals a more substantial, even monumental side to his musical personality. These two settings of the Marian antiphon Regina caeli make an interesting contrast, the first being melismatic and long-spanned in the style of early Josquin while the second is more direct and concise. For SAAT or ATTB soloists or small choir. iii + 12 pages.
