In general I don't approve of companies jettisoning their heritage, so while I am not a great fan of Lavrovsky's version, I wouldn`t like to see the Mariinsky drop it. Likewise, I wasn't especially persuaded by Frederick Ashton's version when I saw it, but it is important in having been created outside the influence of Lavrovsky, and I am sorry it has no home today.
However, I didn't see the Mariinsky's recent London performances of Romeo and Juliet, which came in for a fair amount of criticism, so I can't really judge whether it's become too creaky.
Oh thanks goodness, somebody else who knows ballet companies should not be jettisoning their heritage! Volcanohunter - you are my star! Thank you darling!!!
At least the Royal Ballet is staying true to their heritage whereas the Mariinsky... not so much... People seem to think that the Mariinsky's true heritage is the Soviet-era, but it's actually 19th century Imperial Russia.
