Bach's St. John Passion is the earliest surviving Passion or Oratorio by J.S Bach and was first performed in 1724. This version consists of two sections and retains this structure in the versions and revisions that followed in 1725, 1730, 1736 and 1749. Bach added several numbers in the 1749 version, but several arias from the revisions are found only in the appendices of modern editions. So, there is no 'final' version crafted by the composer as there is for the later St. Matthew Passion, no single manuscript as there is for the Brandenburg Concertos, nor a revised printed edition as exists for the Goldberg Variations. What we do have are Bach's various attempts as he went from performance to performance, to try to grasp what he was aiming for - consciously and unconsciously. There is much that is operatic in the music, and the thought that the St. John Passion is Bach's opera is hardly an original one. This recording uses the new edition by musicologist Malcolm Bruno.
