Irina Kolesnikova was so on top of her technique in SPBT’s one off West End appearance last week, it hurt. Her towering authority and unearthly line swept the artistic board, nevertheless the company sat very well on the Coliseum stage, no longer a brave little troupe deserving a pat on the back, but an established company with both a future and a history of its own. A remarkable achievement for what started out a dozen years ago as a cabaret troupe.
