@Matthew As an illustration of how non-visual my musical appreciation upbringing has been (in contrast with the visually / lyrically dominant Taylor Swift music or VH1/MTV music presentation), only TODAY have I seen Mitsuko Uchida plays Mozart Sonata in video, in this case it must have been an encore (since there is orchestra on the stage): the famous 2nd movement of Mozart's Sonata Facile.

I only hear her Mozart Sonata recording from CDs, here's the same piece from her Decca studio recording. When it comes to Mozart Sonata, I like her rendition the best. Seeing her on stage playing that piece adds only very little to my appreciation of her rendition.
