At the 1989 World Championships the Soviet Union had what I consider to be the dream team of gymnastics. My personal favorite, Svetlana Boginskaya won the all-around, but most striking was how every single Soviet floor routine was its own intriguing little balletic performance (to say nothing of the superior tumbling).
Most notable of all was Olga Strazheva, whose avant garde performance to Stravinsky's Rite of Spring incorporated elements of the original ballet. To put it completely eloquently, the Rite of Spring opened in 1913 and blew everyone's mind because it was scandalously weird.
Here's Olga Strazheva in 1989:
Here's a bit of a Rite of Spring performance for comparison:
Stay tuned for other dream team members.
