England's Orlando Consort, a quartet of male singers augmented as needed by other performers, offers performances of Renaissance vocal music that lie midway between the traditional and the highly individualized modern. Sometimes they veer toward one of those two extremes, but often, as on the present disc, they find a happy medium. Their sound, especially in sacred music, owes much to the English cathedral tradition, but there's a well-honed edge to their one-voice-to-a-part interpretations that brings out the crowds who've recently been drawn to early music. This disc is intended as an introduction to a composer who doesn't always offer easy listening to the modern ear. Netherlander Antoine Busnois, active at the end of the fifteenth century and considered the greatest figure between Dufay and Josquin, wrote music that broke free from elaborate medieval numerology but came in advance of Josquin's perfect marriage of music and text.
