Thanks for the comments, piano121, it was nice reading. Perhaps now, if I get the opportunity to record on the piano, I would dare post some more. What I can say about the recital... It went really well, much better than I had expected or hoped for. I played better than the recording, definitely, although I was pretty nervous.
Okay, about the pieces. The third prelude, in g major, and the f minor etude was the main reason I said that my technique wasn't very developed yet. Listen to Ashkenazy's recording of that prelude, it is a lot faster, and the left hand is played less forte. I can't do it though, I know how I want it to sound like, but I can't play it faster and keep good rythm, and I find it hard to play it lighter. The f minor etude, should also be played lighter with more dynamic variation, and if you listen carefully, my left and my right hand aren't completely together, I miss the beat quite often. I figured it was to late to do anything about this for the recital, and most non-musicians don't think about those things at all.
About the FI, I know there are a few slip like you said, and this is because I've played it too much I think. I ought to go back and practice it slowly again, but I consider it finished now after the recital, and in a year when my technique is better I'll get back to these pieces.
I did record the recital, on a video. It is pretty old, so I'll be having some troubles with transferring it to the computer. When I do, I need to cut it, several minutes are completely uninteresting. When that is done, I might put it on youtube. I'll let you know if that happens.
Thanks a lot,
Jonathan
