Great recording! They may be the most popular as you say, but still underrated in my opinion, especially the scond one. I really like Medtner's recording also, it has a great rhytmic drive as you say.
thank you ! i know in europe and i am sure in russia his music is more played but it will probably never really "happen" over here. that said i play what i love and i love many of his pieces. and many left to explore
