all you have to do is also listen to the clerk's group performance of these pieces. Ockeghem is all about meaningful textures, of which this muddy remaster of a 70s performance is completely ignorant. The top voice is given prominence over the rest, and that is just not Ockeghem's style. I have a very good recording of Ockeghem's Requiem by the same group and same conductor (Bruno Turner) so I suspect things went wrong in the remastering.
