Although the Bolshoi visit to NY in the summer of 2014 seemed like a "done deal" from reading the Bolshoi press release, today's NYTimes, in it's annual Season Preview issue, suggests that negotiations are still underway regarding the engagment. The Times states,
Lincoln Center is still discussing a Bolshoi season in New York. If that happens, the city may see two aspects of David Hallberg — dancing both with Ballet Theater and the Moscow troupe.
I wonder if the non-compete clauses we have discussed elsewhere are an issue here -- not just for Hallberg, but also for Vasiliev and Osipova, who were guests with Bolshoi in their London season last month. As people no doubt remember, that was fatal in the planned Mikhailovsky season last year.
The Bolshoi can sell tickets without any of those artists, though I'm sure the tour presenters would be happy to have them.
I rather suspect, too, that Osipova's contract with ABT may have changed since she is no longer a principal with the company (and in any renegotiation Ardani would presumably have been ultra conscious of the issue).
