At YouTube I just watched/heard Leonard Pennario playing the Rozsa Piano Concerto. It was dedicated to Pennario who gave the premiere performance with the Milwaulkee Symphony. It does have a modern sound, in moments a bit Bartokian perhaps, yet very original and effective. Pennario was a pupil of Isabelle Vengerova who also probably terrorized students Barber, Kallir, Foss, Bernstein, Bonaventura and Graffman among others, but they all went on to have big careers. As when I attended the Pennario recital I mentioned earlier, I noticed in this video that Pennario used to sit such that his forearms, including elbows, were parallel to the floor. The wrists and hands were level as the the tops of the forearms enabling neutrally and naturally extended arms. Through his flexible wrists he allowed just a bit of down flexing of his hands by slightly raising the wrists for playing sequential chords, octave passages and molding slurs. This is exactly what I try to do, as ergonomically it's the safest way to play the piano. Pennario had it all together there.
I'd recommend to others that they hear this Rozsa Piano Concerto if they are not already familiar with it. Being "serious music" so called, it's certainly a departure from his lush film music heard in the "Spellbound Concerto", but it reveals another facet of his genius.
Anyway, I don't want to hijack Chris' thread here, but did want to plug Pennario playing the piano concerto.
I am a much worse hijacker than you are and I have not yet been given the bum's rush, so maybe you are safe for now!
This must have been my first Rozsa and it did surprise me a little, but now I like it too. I believe that to be the only recording and it is no longer available, Funny that, because both Chandos and Naxos have recorded a great part of his music and there are at least four recordings of the violin concerto (and I have them all!) Of his sonata I only know of one recording, dating from the '50s, as for the Bagatelles, I believe Chris's is the only recording available.
That is the best way to play and I wish I could do that too! The times I manage it I cannot believe what happens!
