I used to have Biret's recording of this piano transcription
(http://www.amazon.com/Firebird-I-Stravi ... stravinsky
and recently I bought Lydia Jardon's
(http://www.amazon.com/Firebird-Stravins ... stravinsky
While reading the booklet of Jardon's CD, she said her recording is basically the Stravinsky's own 1910 piano reduction, but with some alterations she got from other piano transcriptions, mainly Soulima Stravinsky's. She refused to use Guido Agosti's transcription (which I myself find very annoying and unmusical), but she likes Soulima's transcription a lot. She said the Infernal Dance she plays is the Soulima's version, which is more luxuriant than Stravinsky's, according to her.
But when I came to Biret's recording, her Infernal Dance has much more notes than that of Soulima version Jardon plays (I'd say Biret version is much more luxuriant). For example, in measure 171 Biret plays hundreds of notes in the left hand. These notes I couldn't even find in the score of Firebird published Schirmer and Dover, though they claim this is the 1910 piano transcription by Stravinsky himself.
I'm really interested in playing "Three movements from Firebird" (Infernal Dance, Lullaby and Finale), but not the Agosti transcription, which is impossible technically for me to play, and also very annoying (much more piano effects than music itself). I was studying this Dover version, which is not easy, but maybe it's not the correct and "full" version. (Or maybe Biret also altered the text, just like Jardon? There is nothing about it in the booklet!)
Does anyone know where I can find this version played by Biret? Or even Soulima Stravinsky's version, played by Jardon? I couldn't find them on Amazon.
And if someone knows another interesting Firebird piano transcription, I'd appreciate too!
