Tosca – Mikhailovsky Theatre, St Petersburg (N0v ’17/Mar ’18)

But it was an Irish heroine who made the piece as, in a performance that was enough to burst hearts, Byrne stole the show, her beautiful voice soaring to the ceiling of the theatre as Tosca was tempted into believing her lover had strayed and subsequently betrayed him.

All effort has been made to make this production an atmospheric one. The singing is spine-tingling at the very least and some in the audience were moved to tears by Byrne’s voice.
