In the title role was soprano Katarzyna Wietrzny, who produced an engaging and beautifully sung performance. Following a fast-moving opening scene, her first notable individual contribution comes towards the end of Act one with a sweet lyrical aria in which she was able to show off the clarity and beauty of her voice. It was her final aria, however, that really allowed her to display her vocal skills. Lasting 13 minutes it requires expressive depth and excellent control. For large parts, the dark foreboding orchestral accompaniment creeps slowly along, whilst the singer carries the melody, in which any mistakes will be cruelly exposed.
