Swan Lake with male swans: Matthew Bourne’s reinvention of the world’s favourite ballet is still a marvel. For this revival, he and regular collaborators Lez Brotherston and Paule Constable have refreshed their staging, but the shape and the urgency of Bourne’s storytelling continue to sing out. This is a Swan Lake that taps into the power of the classic the yearning for love, for freedom while finding its own spellbinding imagery.
