KEY POINTS:
Bach's Mass in B minor is a choral monument and a mysterious one. Why did Bach, a Lutheran, write a Catholic Mass?
Why was it not performed in his lifetime?
The Mass receives its first Auckland performance for a while with Bach Musica on Sunday, 5pm at the Holy Trinity Cathedral, under the baton of Rita Paczian and a quartet of soloists in Nicola Edgecombe, Kate Spence, Patrick Power and David Griffiths.
