The complete recording on CD is occasionally available from Amazon and others. I have one and it is striking. Djansug Kakhidze, and the USSR Radio and TV Large Symphony Orchestra in 1976. You should get one. There are several recordings of the same performance on Russian Disc, VOX, Mobile Fidelity, etc.
I also have a very rare complete LP set of the ballet by the Moscow Symphony Orchestra conducted by Dudarova. I just received it and have not played it yet. 1987
SEarch under all of the names: Gayne, Gayeneh, Gayane
The complete score varies with revisions by the composer so it can be 48 to 54 movements. I have the full piano score. It is almost up there with Swan Lake in music, not in choreography.
