Rachel Nicholls’s Brünnhilde is a strong, shining, secure sunbeam of a soprano, and a dramatic joy too, progressing from eager demi-goddess to vulnerable woman, transformed by the vision of human love provided by Siegmund. Lee Bissett proved a complex and unforgettable Sieglinde, devastating in her final utterance of the ‘redemption’ theme. Alison Kettlewell’s poised and vivid-toned Fricka won sympathy, reducing her Wotan to humiliated pulp.
