Actually, it needed pitch lowering from 444 to 443Hz. I have no idea who could come up with such a stupid idea - and leaving the top two octaves at 443Hz. Brahms Intermezzo A-major Op.118 No.2 for some stress relief.
Great performance and recording. Perhaps the piano was exposed to the elements? When this happens, I find the pitch either goes high or low according to the weather / humidity, ETC.
