Just when you think you know somebody, some uncharacteristic behavior shows itself and you instantly realize that you have more to learn. Such an enlightening occurrence is bound to happen for listeners to this disc accustomed to hearing the "memorable tunes, regular phrasing, and clear harmony" of Machaut's most commonly performed works. Here, the four-member Orlando Consort--alto, two tenors, and baritone--happily and with masterful ease introduce us to the "other" Machaut, one of irregular phrases, lively syncopated rhythms, and long flowing melodies that interact contrapuntally with two or three other vocal lines. The melodic structure often consists of cleverly intertwined strings of suspensions followed by quick resolutions, giving a jumpy impetus to many lengthy passages and entire songs. Among these 14 secular songs are many beautiful poetic texts and some notable melodies, but, interestingly, Machaut didn't attempt to fit music with textual meaning. For us, it remains just to listen--and perhaps to read the words separately--and we are rewarded with some of the 14th century's most sensuous, intriguing, and exotic music. --David Vernier
