Thanks for this, Catherine. Very interesting that this short tour isn't mentioned on the Mariinsky's official website, making me wonder if this might be a freelancer/pick-up company? Three of the listed corps in Salome
are not on the official Mariinsky corps de ballet (not just 'sister Somova' - also Natalia Sonova and Vladislav Smakov). http://www.mariinsky.ru/company/ballet/kopdeballet/
(I even checked the Reserve and Extras departments)
Maybe they're part of the "90 new corps members" that will be added in Fall 2013 (result of the recently-announced audition)?
A few color photos of this tour can be seen at the bottom of the following Italian interview with Faski, the choreographer of Salome
(which, I think, premiered at the Young Choreographers' Workshop at the MT in March):http://www.danzaedanzaweb.com/articolo/212/
(posting because of the photos; not the article, which is not in English, I realize)
The last photo of a couple in flowing white outfits appear to be Brileva and Ermakov as Salome and John the Baptist. Schlyarov is seen as Apollo, etc....
