Hi pianistimo,
Great to hear from you again! You were missed here on the forum.
I really appreciated your saying that I play these pieces probably as Bortkiewicz intended them. In his lifetime, although he was a virtuoso touring artist, Bortkiewicz refused to play his own piano works in recital. (Rachmaninoff, of course, showcased his own pieces and greatly promoted and popularized them through his recitals, which boosted his career and fame too.) So it fell mostly to the Danish artist Hugo Van Dalen to champion the Bortkiewicz repertoire on his tours. Bortkiewicz died in 1952, and that repertoire soon became nearly completely neglected. Because that was over a half-century ago, the performance practices were lost. We're just acquainting ourselves with the dusty scores now. When I undertake one of his pieces, I develop my own interpretation from scratch. One exception was the Impromptu "Eros", as I had heard Koji Attwood's rendition here before I studied it; yet, he and I both believe our interpretations of the piece are very different. Anyway, in working up such an interpretation, I am guided by the one ultimate criterion: "If Sergei Bortkiewicz could be here to listen to this interpretation now, would he be pleased?" That's it. If I feel the answer is a yes, I post it here.
The piano was rebuilt a year ago and is only now reaching stability. It was last tuned in May. But since then I've been punishing the piano with Scriabin, first the stormy "Poeme" Op. 32, No. 2, and now I'm practicing the big "Poeme tragique", Op. 34. So earlier in the summer the piano was really in "bloom", but now it's getting out of tune again which invites those slappy and ugly overtones. If it were freshly tuned, I think you'd like the sound better. Another factor might be that when you were last here, I was still doing analog recordings, but have since switched to doing digital recordings. Although I love the added clarity and perfectly silent background of solid state technology, analog had a warmer sound to it. So I wouldn't discount that difference in what you're hearing.
My Bortkiewicz recordings, seven of them now, are spread over pages 1 to 5 here. If you've missed any in your absence, pianistimo, please do have a listen to them. They're all so different, and I think you'd really enjoy hearing any you've missed.
Thanks for listening and commenting!
