Finished up Insónia today and going to post it later.  There's a lot of finger noise, but I'm pretty impressed with how well I played it.

Played more than practiced today, but did work on technique with Prelude 1 to see if I could adjust anything so my hands don't cramp up after more than one playing.  I found my right thumb needs to move differently - 2nd knuckle of thumb aimed towards 1st knuckle of 1st finger in the upper registers is the best I can describe it. This means my hand is at a different angle, too.
