Have you ever seen this?: Glenn Gould: Bach - Goldberg Variations The video of the actual recording session.
The most amazing pianist I've ever heard was Alicia de Larrocha....her recordings of Granados' "Goyescas" are legendary. Here's a sample
I had the good fortune to meet her in 1969, when I was stationed in Spain. What astonished me then, and still does to this day, is how very tiny her hands were..incredibly small. I've played some piano, of and on over the years...I can palm a basketball...and when I shook her hand,her entire hand fit inside my palm. I can't believe she could generate such power, let alone reach all the chords. I don't know if she ever attempted Liszt...it would have bee a "stretch" for her
Thank you for that!
