Ockehgem's lament for Binchois. Schmelzer is rather controversial. I thought his Machaut a bit crazed but I do like this.
Binchois just plain lamenting. Also Schmelzer. Beautiful for sure but to me this one is less convincing. It sounds too modern, and a bit prettified. So here a 13th century chanson I find just right.
One for the road.
UPDATE: I am not a musician, so struggle to explain what bothers me about Schmelzer. It sounds too modern somehow, too granola. Anyway here is an interesting analysis.
Their Josquin works well I think, especially the start.
So for comparison, Dominique Visse's group here. I think this has a strangeness that it should have. I have heard this group perform this live, so might be prejudiced.
I suppose the reference recording is the Hilliard Ensemble.
The Orlando Consort is also splendid.
The King's Singers take a more stately approach.
