although not hindered (regrettably so) by technical knowledge nor by
musical education, I fully agree with the nomination of this composer.
This on the basis of my enjoyment of his Concerto for Piano. And to a
lesser extent the complete pianomusic, wich I play a little less often
than the mentioned concerto, but which I never the less like very much.
