Haven't posted in here in a while...
I performed (informally) a few pieces past couple weekends:
Czerny Art of Finger Dexterity #8 in a minor for LH - it's 90% memorized, is musically easy, so went pretty well.
Brahms Op 119 no 4, Rhapsody - not memorized nearly well enough, so with the new piano and performance stress, I was thrown off a bit more than I expected. It went well in practicing, but I should have done some recording to mimic the one-time-thru performance scenario.
Chopin Scherzo no 2 - some sections are memorized - those went fine - the ones that are not memorized did not go fine ...

You can see where I'm going with this...
