I saw Preljocaj's Le Parc this Saturday at the Paris Opera Ballet (and many thanks to this forum, without which I never would have secured tickets!). I really enjoyed it - I found it thought provoking on many levels and very responsive to the Mozart score in a new and unusual way. Laëtitia Pujol was the lead ballerina, and she was very convincing in the role - she had a wonderful plastic sculpted quality to her dancing and was very emotional in the withdrawn way that the role requires. Stéphane Bullion was a last-minute sub for the lead man, and while he handled the part fine, it was nothing particularly exciting. The orchestra was very impressive - and Mozart can be very difficult to play since it's so exposed.
I was also delighted to see the Opera Garnier - elaborate doesn't even begin to describe the theater! Everything was over-the-top stone sculptures and decorations. In all, it was a real treat.
