Johann Ludwig Krebs, born in 1713, occupied a special position among Johann Sebastian Bach’s pupils. Bach, who was music director at St. Thomas’s Church in Leipzig at that time, obviously thought highly of Krebs, who was his private pupil and copyist for nine years. There was a contemporary pun on the German words “Bach” (stream) and “Krebs” (crayfish): “In this great stream only a single crayfish has been caught.” What could be more obvious than to devote a concert programme to the two masters?
