The Sixteen and Harry Christophers confer class and professionalism to the point where it is difficult to be critical, so why bother? This is the first volume of an overdue representation of Palestrina's 16th century papal music. Renaissance polyphony delivered in the expert hands of Christphers and his Sixteen. Followers of their previous output will know that the level of performance is nothing less than outstanding. The framework is based upon 'The Assumption' and 'Song of Songs' alluding to the 'Virgin Mary'. The magnificent textural intertwining of the vocal instrumentalists are a mastery of the understanding of the participants in their fifteen poetic passages. This is a further luxurious addition to their choral output and more awaited. A majestic achievement.
