The Grand Pas from this ballet was reconstructed by Vasily Medvedev and performed at Dance Open; a rehearsal video has turned up on youtube:
Does anyone know anything more about this ballet? What is the context of this Grand Pas? I'm wondering what the doors with 'past', 'present' and 'future' above them in the backdrop signify.
Edit: another video of what appears to be the coda. Filming quality is not very good, but it gives an idea.
