Hi Dave,
Thanks so much for all your kind comments. You know that when one posts a piece like this, there is no way to know whether it'll be a success or a bomb.

So I appreciate your validating comments! Coming from a fine musician and artist, it means a lot to me.
Medtner certainly does have a rich, complex, and difficult idiom. The harmonies within chords at times seem as prominent as the horizontal melodic line that those chords often form. At times it brought Debussy to mind. It used to anger him when pianists chose to "voice" or etch the line. Debussy insisted that he preferred that all of his colors be heard without emphasizing the melody per se. I sense there is a some of that same intention in Medtner's composing.
When it comes to repertoire, I think I was born to play mostly Russian and French music. I never considered myself to be nearly as good in the Germanic piano literature, so generally avoid it. While Medtner was Russian born, he shares a trait with Catoire. Catoire was Russian born too, but French influences were in his blood. Likewise, Medtner was not devoid of his German heritage and influences, especially given his high esteem for Beethoven. There were many times in playing this sonata that I felt I was back with the music of Beethoven and Schumann again. I quickly discovered that Medtner never met double-note passages that he didn't love at first sight. But like we always say, a pianist can never get enough double-notes, and Medtner gladly obliges.

"Catching the imagination", as you so rightly put it, was always my goal at any moment in this rhapsodic music. The moods and emotions shift quite often, as Medtner shows us more facets of Bratenshi, and I tried to grasp the essence of each as the piece unfolded. In "singing" this sonata, I took some risks... which resulted in some slips, unfortunately. I tried to blend them in as well as I could. As you know, I don't edit my recordings. The irony is that some of those errors I had not made previously.

And I don't think it's a simple matter of practicing. There is a spirituality in the moment of performance that urges taking risks, which lie outside the mold of practicing. And the music is so complex that when I would fix one problem, another would crop up later in the music, again from taking a risk. That could have gone on forever, so I decided, for better or worse, to record the piece and just do my best. I'm the first to admit that I never had a big technique, so I simply try to capitalize on the strengths I do have.
I should mention that this piece calls for endurance as well. By the time I'm into the coda, my hands feel worn out from pushing through Medtner's thick textures. Germanic music is often rambunctious and takes energy to put it over to the listener. In all honesty, I'm probably better at lyrical music of other composers. Nonetheless, this was a wonderful experience for me, and I'm glad I did this sonata.
Thanks, again for the compliments.

David
