The other day I performed the Clementi Sonata in f minor (Op. 13, No. 6) that I had previously deemed so bizarre as to be unplayable. It turns out to be nothing short of a knockout.
Imagine my surprise to find that this very sonata was played by Vladimir Horowitz who, in so doing, put Clementi onto the modern map. Imagine! The pianist whom I would least have suspected of such audacity accomplishing this most stunning achievement!
