Dance is brutal. And dance is gymnastics. But this is another whole level. And you notice there are no tall people, no long legs here. It just blows my mind.
Leave it to Asians, inspired by American culture, especially inspired by black culture, this did all have its roots in black culture, first seen in N.Y. street dancers, buskers of a kind, would set up their boombox, and set out a flat piece of cardboard on the sidewalk suitable for spinning and dancing an entirely new way and quickly adopted on the west coast, developed further in idiosyncratic styles, but leave it to Asians, particularly Koreans to apply their studied coordination in teams under tutelage of master choreographers. I've known ballet dancers, and I've seen a lot of ballet, but I've never seen Mikhail Baryshnikov pull anything like this. He's a big fairy compared to this.
And on the other side of the globe, across the Atlantic, it's France that is inspired by American inventiveness to take it all to another order.
