I have an old Olympia disc featuring my favorite Piano Trio...of all time! (cue Muhammad Ali impression) Sviridov's trio was written shortly after DSCH's, and contains ALL the things...I'm telling you I've searched in vain for a more perfect Shostyesque piece of chamber music. The slow movmt has all the same great stuff as Shosty, and the whole has that nostalgiac look back on things forever lost (Myaskovsky's Cello Cto.). I don't think you can fault him for having every note in place here...best Russian P.Tr. ever,...drink lots of vodka and cry.
Next on the cd was some songs or vocal music...which I still haven't listened to, well, maybe once, but I'm sure it doesn't exhibit the "beautiful" aspects of Sviridov (if it had the same melancoly as the P.Tr. I'm sure I would be raving now). I'll have to find it.
Last on the cd was I believe a Chamber Symphony which I believe was a more optimistic upbeat affair (why am I thinking Casella?). I think it had some modern touches, vigourous, rompy, and just attractive as music. Good old fashioned substantial mid-century modern Russian composer music.
But anyone seeking "the" Russian Piano Trio need look no further!!!
I remember being disappointed by Vainberg's Piano Qnt. because it did not meet up with my minor key/Shosty expectations (though Vainberg's Cello Cto. certainly is perfection). Perhaps Popov or Shebalin...?
