The legendary Kirov Ballet returns to America. Tobi Tobias: “Granted, today’s Kirov corps is not the ensemble it once was, with every head inclined just so, every wrist angled exactly, every leg raised in arabesque to some preordained height, the uncanny unison work not mechanical but buoyed by the music. Still, the current group resembles the corps de ballet of the old days in kind if not degree, and it is a fine sight to behold. The rest of the dancing was dispiriting.”
