The use of all-male voices, and in fairly small numbers, gives these performances a special kind of authenticity no doubt. Yet there are some problems of balance in the reverberant acoustics and intonaton does occasionally stray in the solos. The CD allows cueing to all five sections of K317 and the much shorter K220 Mass, arranged in that order with the Offertorium sandwiched in between. A CD for Mozart religious-music enthusiasts only—who will welcome the authentic style in this seldom-recorded repertoire.'
