Both Russian-trained sensations. She of the Kirov, he of the Bolshoi. Both Soviet defectors. I never saw him dance in person. I saw her dance many times, with ABT. Note his one-armed lift (of her) at 0:53. Note her turns — every last one of them. Her turns breathe. See her (twice-executed) en dedans pirouette, 01:55; it cascades into a hard-to-fathom chain of motion ending in a sumptuous, supported back bend. This is ballet classicism at its zenith. You don’t see this mix of steely technique and regal bearing any more, not really.
His posturing and partnering. Her placement: precise, resilient, reliable. It’s exquisite. The molasses tempo! An inside joke, doing Don Q that slowly makes it that much harder. Did we know at the time we were at the top?
