The Vancouver Bach Choir is wrapping up its 85th anniversary season with a bang. The renowned choir will perform Johann Sebastian Bach’s St. Matthew Passion at the Orpheum this Saturday (March 19) alongside the Vancouver Symphony Orchestra and a group of internationally recognized soloists that includes soprano Anne Grimm, bass baritone Alan MacDonald, and tenor Benjamin Butterfield. Written by Bach for a Good Friday mass in 1727, the commanding piece entwines song, drama, and text to tell the story of Christ’s betrayal, trial, and execution.
