My first listening of this CD was mesmerising - the music is beautiful and it is gorgeously sung. The Fors Seulement Chanson by Ockeghem is very moving and so is the mass of the same name. Whilst the Requiem is the more famous piece, I found it less warm than the other pieces on the CD. All in all this is a trully great recording. If you are interested in polyphony, then this is a must for you.
