The vulnerable young woman at the heart of Janacek's breakthrough opera is a signature role for the English soprano Amanda Roocroft. Here, in Stéphane Braunschweig's clear but deeply affecting production, she is partnered by the Slovak tenor Miroslav Dvorsky, as the man through whom she finds redemption, love and hope. The complex figure of the Kostelnicka becomes both tormentor and tormented in this fearless interpretation by the great dramatic soprano Deborah Polaski.
