Alla Sizova was an uncomparable Aurora,but her Giselle is another story.Technically there were no hurdles.
She was light as a feather,practically weightless,but she didn't move you,didn't make you weep the way Bessmertnova did, especially when she was partnered by Baryshnikov. Sizova was actually Baryshnikov's first Giselle,but there was no chemistry, no fire you could feel when he danced it with Bessmertnova, and later with Makarova or Kirkland in the States. Of all Kirov Giselles, Yelena Yevteyeva ,though not the greatest Giselle,but a excellent one,was better suited to Baryshnikov,than Sizova or Kolpakova(another great Aurora if not the greatest,but again,though technically perfect,did not belong to the list of great Giselles). Alla Shelest ,of the older generation of Kirov dancers,was by all accounts both- a great Giselle and a great Aurora. She was young Nureyev's favourite partner at the Kirov,the exact contempary of Fonteyn,both being born in 1919.
