Bach (pronunciation) wrote his Choral for organ BWV659, Nun komm’ der Heiden Heiland. A rather nice interpretation is on youtube. Never mind the boring video, it is a audition for the Geneva conservatoire, so fiddling with a camera would probably NOT be a good idea.
Then, more than a century after Bach’s death Italian composer Busoni came along. He (oh blasphemy) arranged quite a few pieces of Bach for piano. Remember that in Bach’s time, the harpsicord and organ, both non-dynamic instruments, meaning, impossible to change the volume by the way of playing, were the prevalent keyboard instruments and only late in his life, the Silbermann piano, predecessor of the modern piano, gained ground. Here is late Vladimir Horowitz romantic interpretation, played in his own home. It’s a cut out from a 1.5 hours documentary.
I love this, listen to it every day, a soul connection.
