Carlos Acosta has tweaked the classic Petipa choreography and seeing it so soon after Mikhailovsky Ballet’s performance of the original gave me a good chance to spot the improvements he has made. A new prologue helps the story make a little more sense but the main change has been to loosen up the choreography, allowing a smoother more naturalistic feel. Minkus’s music has also been arranged and re-orchestrated by Martin Yates. It was a great improvement on the earlier performance, although I am not sure whether that was down to the new arrangement or the superb playing of the Orchestra of the Royal Opera House under Vasko Vassilev. Either way, there was more humour in the music where appropriate and more passion when required. I saw the matinee performance so didn’t see the star casting led by Acosta himself. Still, Alexander Campbell and Roberta Marquez were excellent as the leads, although the latter was almost outclassed by Laura Morera’s superb performance as the street dancer.
