Yes, I know it's not piano, or even a Composer, but I stumbled on this today and its amazing! If you struggle to use just one pedal then, check out this piece by Bach. Cameron Carpenter makes it looks absolutely effortless. This piece wasn't actually written for the organ, so would have originally been played on a harpsichord, and these days it's usually played on the piano.
For those of you with electric pianos, what is your favourite piece played in Organ mode?
