gasp, I had missed this when you first posted it. luckily I saw it when you posted book 2 c minor. anyway, it's obviously a quite famous one, and one that I think most people learn relatively early in their journey through the WTC. as such, there are a number of sub-par interpretations swirling about the internets. yours is not one of the above though--as usual your bach is first-rate, and I really like what you've done here. for the prelude, the tempo is perfect and the line is perfectly steady, which is critical in a work of this nature. the fugue has your typical clarity of line and voice separation which sounds effortless, but which I know from experience is a rare gift (one of which I am woefully not possessed).
