I'm astounded this fine CD has yet to be reviewed. This is, to my ears, the best the Huelgas Ensemble has ever sounded. The three masses are presented strictly vocally in very pure performances, Van Nevel allowing the music to speak for itself, leaving all eccentricities aside (except perhaps for the programming). The Huelgas Ensemble's intonation, phrasing, balance, and blend is spot on, and the CD is gorgeously recorded. (Though more reverberant than my usual preference, sacrificing some clarity, it works quite well for me here, with the voices so perfectly blended and transparent.)
The three six-voice masses on the CD were deliberately chosen to contrast with one another: The masses by the two contemporaries Palestrina and Lassus representing the Roman school and Franco-Flemish style, respectively. Merely programming music by these two masters on the same CD would in itself have provided an interesting contrast, but it is with the mass (from a couple of generations earlier) brilliantly sandwiched between them that this CD really shines.
You simply must hear the Ashewell mass, representative of the "English Late Gothic" style. It is easily worth the price of the CD alone. Quite startling -- but very effective and musical -- false relations abound! It features great variety throughout all four movements (he did not set the Kyrie), and the writing is often particularly creative rhythmically. But it also features soaring, expansive melodies that knock me out. I have never heard anything else by Ashewell (also Ashwell). He lived from c. 1478 to sometime between 1513-27. Apparently there are only two complete extant works by him, both masses. At the end of his life he served as cantor at Durham Cathedral (what a place to work! -- if you haven't been there, but have an interest in it, you really should go).
Two quick notes:
1. Fourteen singers were used for this recording.
2. The Credo of the Palestrina mass was omitted for reasons of space.
