Mr. Buchbinder plays at the piano, conducts the orchestra, brimming with confidence ... and with smiles. Beethoven might have done the same, performing while conducting, over two hundred years ago ... but, I would venture a guess, that Beethoven did with more seriousness on his face.
Both video and audio are enjoyable to view and listen. The lighting is sufficient. Blu-ray recording gives more pleasure to the eyes viewing the performers at full concentration, and Buchbinder's impressive finger works. He makes my finger twitch (in a good way, of course).
