Kommst du nun, Jesu, vom Himmel herunter (BWV 650) and choral (Bach setting).
As most often the case with Bach organ music, this is by far not the first CB upload of BWV 650. But, I believe this is the first time on 'Martini'.
Often this piece is played in a higher gear, but that would be beyond my capabilities... Hope you enjoy this beautiful choral prelude anyway.
