Cleopatra, the fabled queen. Salomé, the temptress. Ophelia, Shakespeare’s gentle, lovelorn heroine.

And that’s just the start of it: Thomas Søndergård joins Scotland’s international award-winning mezzo Catriona Morison to unleash floodtides of passion in an all-French evening inspired by the sea. When Chausson, Ravel and Debussy gazed at the waves, they each saw a different kind of beauty: let them sweep you away tonight.
