Swan Lake- Kirov/Mariinsky

[MakarovaFan]

I own the dvd of Mezentzeva/Zaklinsky dancing Swan Lake with the Kirov. In that production the harp cadenza for the Act II PDD is unique. Anyone know who wrote it?

I think that harp cadenza is a Soviet-era addition, but I've no idea who composed it. It must've been one of the conductors or directors of music or someone from the music department at the Kirov/Mariinsky Theatre.
