[Machine Translation] German composer Johann Peter Kellner is now credited as the author of J.S. Bach's "Suite for Unaccompanied Cello". Some even claim that he is the true author of the famous Toccata and Fugue in D minor, BWV565. As the episode suggests, he was very close to the Bach family, and despite his short musical education, he is said to have mastered a high level of compositional techniques. This series of cantatas, premiered 250 years after Kellner's death, are majestic works in a late Baroque style similar to that of C.P.E. Bach and G.H. Stolzel. In this performance, the "Kellner-Weise Organ" (restored) from 1736 is used, and the atmosphere of the period of composition can be fully appreciated.
