Bach Prelude and Fugue in B flat major

I first learnt this in 2011, so it was an old friend when I came back to it. This did not make it any easier to record! I usually have 3 or 4 attempts and choose the one that most conveys the music. I think this was the fastest version I recorded, and there are one or two slips, but overall it is how I wanted to play both the prelude and fugue.
