Thirty years ago the Bolshoi Ballet's first trip to America was a political and artistic triumph and audiences queued for days to see these legends of ballet. Bolshoi in Vegas, a richly entertaining documentary, follows their disastrous 1996 tour in which they hoped to capitalize on this earlier success. Kirov in Petersburg traces the development of an institution, which is both irremediably altered and condemned to trade on its past glories. As Communism gives way to Capitalism, the Kirov Ballet's chief choreographer Oleg Vinogradov's final year in office is set against allegations of bribery and corruption.
