Actually, I put up an earlier account of the prelude but in a different forum at P.S., about a year ago, I think, which I recorded at my new piano with new equipment. That's gone now from "the box," so you can't listen to it to compare. It's would have been close to this one.
In any case, the C Major prelude is brutal, in my opinion. I've tried to figure it out over the years and I have pretty much given up. So much in Book 2 is unfathomable, yet gorgeous of course. However, I did find this particular version on my desktop, where I tend to store various attempts I've made of various pieces over the years. I listened to it again and thought, "This is not so terribly bad after all." Even though, quite frankly, I still don't understand the piece.
This version I did at the keyboard on a sampled piano. I regret to say that I prefer this performance to the other more "real" one I posted at a different forum here (to demonstrate the accuracy of self-tuned pianos, if I recall).https://www.box.com/s/rym9tgh88dyb8y5id3vc
