Bach's Mass in B Minor is one of the pinnacles of Baroque sacred music and a mighty challenge for any choir.
Created during a period of some years at the end of the composer's life, assembled from works already written, it was not heard in its entirety until 74 years after Bach's death. Yet for all this musical patchworking, the score has a remarkable inner cohesion and stands as one of the loftiest testaments of the Christian faith.
I last heard Rita Paczian and Bach Musica NZ perform this work in its entirety 12 years ago; at Sunday's performance, we were denied the 30 minutes or so of its Credo, an excision neither explained nor justified in programme notes.
Apart from the liturgical issue of removing all-important doctrine — is this a mass for non-believers, one was tempted to ask — we missed out on some of Bach's most captivating music including the powerful Crucifixus chorus.
Key arias were also unceremoniously shunted, along with the final rousing chorus - a highlight of this group's 2007 concert - heralding with joyous trumpets and drums the resurrection of the dead and a glorious life to come.
