In his extensive review of Xavier Roth's new set of Strauss' "Sound Poems" - I am trying to help out here by rehabilitating the correctly translated name - Gwyn Parry-Jones mentions in passing that he is unsure whether the live 1947 recording of the above has been released on CD. I have it in a good transfer on the two CD set "Furtwängler - Maestro Classico vol 2" on the History label - along with, incidentally, his live recording of the Sinfonia domestica - a work of which I have a higher opinion than Gwyn!
