The worst thing about Johann Sebastian Bach’s various Passions—devotional works dedicated to the lives of the great evangelists—is that at least two of them have gone missing during the centuries between his time and ours. All the more reason, then, to revel in the Vancouver Bach Festival’s sumptuous production of the master’s St. John Passion, from 1724. With Alexander Weimann directing the Pacific Baroque Orchestra and the Vancouver Cantata Singers in support of an all-star cast of soloists, a trip out to the Chan Centre for the Performing Arts on Friday (August 11) will be very deeply rewarded.
