Some conductors have a special affinity with a particular piece of music and that’s the way it is when Jeffrey Thomas steps up to conduct J.S. Bach’s B-Minor Mass. He takes you through this piece as if it were an actual journey, a real mass, instead of a compositional tour-de-force that is far too complicated and long to present as music for a religious service. When American Bach Soloists do this piece, they’re at their best, like their conductor. You can miss it, but you’ll be kicking yourself in the morning.
