In view of the fact that several of the works are composed for double choir, the usual 16-member choir from the cantata recordings have been slightly expanded to 18 singers, of which some also appear as soloists. Included on the disc are the six motets BWV 225-231, as well as BWV 118 O Jesu Christ, mein’s Lebens Licht and BWV Anh. 159 Ich lasse dich nicht.
