Thus far today, I've gotten some stuff organized and put away and got some new music to work on more or less organized (some people still owe me some). Then I fell into a rabbit hole downloading some scores from IMSLP. I'd never used that site much, and shame on my sorry ASS because that's going to change. It's incredible what can be found there.
One thing I wanted that isn't yet in public domain is Poulenc's Le Bal Masque, preferably the full score, but a piano solo version would do.
Another is Gershwin's own Porgy and Bess Suite ("Catfish Row") -- not to be confused with Robert Russell Bennett's "Symphonic Picture" or any other arrangement. This one strongly features some of the purely orchestral music from the opera such as the fight fugue, hurricane music, and an abbreviated version of the opening piano solo.
