Everyone,
As far as I know there's no trace of any recording for the subject work, nor any upload from any live performance or piano reduction, whatever, even amateur performance.
Should anyone have a different understanding would they be so kind and point me to even a s old out old recording or any online fragment?
It's a shame such an ambitious work is completely forgotten and unsung!
THanks
From a quick search via Worldcat.org, it appears only the Prière from the Symphonie has ever been recorded.
