"Among the distinctive details here are that it is performed at probably the lowest possible pitch ... The textures in general are exceptionally clear and, partly as a result of that pitch, the lines are beautifully relaxed ... Another special delight here is the inclusion of the Proper chants for the Mass ... As a serious eccentricity, the polyphony is sung with a French pronunciation of the Latin, but some of the priest sections are sung with Italian pronunciation ... Sounds a lot better than most priests I have heard, but this is taking historical style to a new extreme".
