If you can find it, try to find the VAI DVD with Kolpakova in a 1980 live performance. It's the Kirov/Mariinsky version.
This is my favorite performance video of anything.
YouTube doesn't have the complete, but it does have some excerpts from 1976:
Her partner here is Semenov. In the video it's Berezhnoi.
There's also the video excerpt from the DVD, which I missed the first time:
I fell in love with Irina Kolpakhova whilst still at school when the Kirov Ballet visited London for the first time. I was very new to ballet and a new knowledgeable friend of the time convinced me I should see the company and I in turn convinced my mother to fund my visits to amptheatre and the standing room.
As a lover of London's best classical architecture, I found a reflection of such high art classicism in Irina Kolpakhova's
linear crystaline distinctiveness in both the structure and outline of her dancing. Add to that her musicality and nobility it was no wonder Dame Ninette de Valois enthused so much over this ballerina's perfect classicism.
Madame Kolpakhova's classicism seemed other worldly to me and yet here she was appearing among an extraordinary galaxy of star dancers vying for excellence and thrilling audiences and critics alike.
I agree with Helene evaluation and I find Kolpakhova remarkable in this video given she was 43 years of age.
