Hi ronde,
Thanks so much for posting this beautiful etude! I think as pianists, many of us become so focused on Rachmaninoff and Scriabin, that other Russian late and neo-romantic composers like Liapunov, Liadov, Arensky, Medtner, Catoire, etc. seem, regrettably, to get lost in the background. This Liapunov etude is absolutely ravishing--lush and chromatic with ever-shifting tonal centers, enharmonic changes, deceptive cadences, etc. You play this piece with a marvelous technique and make every note of it expressive. Your phrasing is superlative. From listening to the accoustics, I believe a big challenge for you was the hall itself--it has a very "live" sound, but you compensated for that well. I'm sure that this is not an easy piece to learn, but adding this one to your repertoire will turn out to be a fine musical "investment", I'm sure. Great music and a great performance!
Were you playing a German Steinway or a Bechstein? I couldn't quite tell.
