Bach composed the St. John Passion for Good Friday services in Leipzig in 1724, and it remains a testament to his brilliant genius and emotional depth. Though more intimate than the St. Matthew Passion, this setting of the story of Christ’s death is no less moving. Austin’s first period-instrument performance of the Passion in a number of years will feature several of ABO’s talented vocal and instrumental soloists in a Lenten concert, the ensemble’s first presentation of this monumental work.
