This recording of the Mass for St James the Greater by the Binchois Consort makes the music sound like what you expect from early Dufay. There are some really beautiful moments, but on the whole the mass doesn't seem to have the psychedelic intensity of the motets on the same CD, which are really special.
That's all well and good, especially because Binchois Consort are excellent at Voix Égales style balances, except that there's this puppy, the St James Mass from Cappella Pratensis.
They slow the music right down, and in some way I haven't quite understood they have smoothed the music out: it sounds much much much older, more sedate and prayerful and introspective in a way that recalls the effect of some 13th century music. The downside, and I can imagine that for some this may be a deal breaker, is the relative absence of dramatic contrasts within sections. For me there is contrast enough, but only just.
I must say I find the tempo of Capella Pratensis really challenging, but that's not really important because I know I'll adjust my expectations once I forget Binchois Consort. My intuition is that CP find the elusive heart of the music, but I'm no expert.
At any rate I can say that these recordings are really stimulating because so very different.
