Choralvorspiel "Lob sei dem allmächtigen Gott", BWV 602 (from: "Orgelbüchlein")

Even though probably no one here on Contrecombarde needs another recording of a chorale prelude from the “Orgelbüchlein” by Johann Sebastian Bach (1685-1750), I couldn't resist recording the chorale prelude “Lob sei dem allmächtigen Gott”, BWV 602, as my probably last advent “finger exercise” this year.

There are two reasons for this: firstly, I have actually never played this piece before; and secondly, I find it highly fascinating - and I will explain why in the first comment!
