Hi and welcome. I agree, Medtner is an awesome piano composer. Pity that most of his pieces are too difficult for an amateur to bring off sufficiently well. I've played a lot of his music, including most of the Fairy Tales, but never dared recording any except for the easy Ophelia's Song.
That is a good performance you give there. This is one of his more straightforward pieces but still quite a handful. Well done.
Well... would you like to share you recording also?
I wish people could play more of his music... It is a big pitty.
