Probably quite old news now, but worth mentioning again. Thanks to Open Culture
I wonder who will perform the lute music?
Bach wrote 1080 compositions during his lifetime. And now thanks to the new and certainly ambitious All of Bach web site, you can eventually watch the Netherlands Bach Society (founded in 1921) perform each and every one of those compositions.
By the way, that opening piece on the video is an interesting organ transcription of a cantata Sinfonia (Wir müssen durch viel Trübsal, BWV 146) based on the D minor keyboard concerto BWV 1052 which is probably in turn a transcription of a lost violin concerto and which I transcribed for a Naxos recording
