An american at the Bolshoi

­The main stage of the famous Bolshoi Theater has opened again after a six-year-long renovation. And the theater’s company has changed, too. For the first time in the Bolshoi's two-century-long history, a foreigner has been hired as principal dancer. Critics say it's the beginning of a new era, others argue it's the end of the Russian ballet. So why did the Bolshoi's management take this unprecedented step? And what's the future of the top Russian theater with a foreigner center stage? We ask one of the world's most famous ballet dancers and the Bolshoi's new premier – David Hallberg himself.
