I have two versions, both coming as part of boxed sets of 50 CDs or whatever.
Both are excellent to my ears, but I didn't really know the music, apart from the lament of course..
Emma Kirkby, Catherine Bott, Hogwood
and Anne Sofie von Otter, Stephen Varcoe, Pinnock.
Maybe I very slightly prefer the former - and I can't really imagine anyone else's being much better.
