Query: A fine interpretation of this masterpiece.

Ensemble Organum seem to use voice which are not "Classical Music" voices in the normal sense of the word. However, this is a phenomenal interpretation of this work, although it is not quite as "avant-garde' are their recording of the Messe de Notre Dame of Machaut, which is just something else! (I love it, BTW)The pitch of this work has been transposed down, although it should be said that there is no real absolutes vis-à-vis pitch in music like this. I have the Pro Cantione Antiqua recording of this work and until I heard this recording, no other recording tempted me.This recording tempted me and won me over.You should try it, too!
