I came across this piece while looking for Hamelin's second recording of Alkan's concerto, and now as I am finishing the presto movement Bach's Italian Concerto, I'm thinking of learning some of them. I'm not sure if I have the technique to play these pieces, though.
[edit: Before this I've also learnt Beethoven's Piano sonata No. 3 in C major, Op. 2, No. 3, 1st mvt, but nothing more.]
