Michaela Martens press reviews
The much more severe and publicly respected Kostelnicka was magnificently portrayed by Michaela Martens...[she] handled both physically and vocally the transformation from high-handed custodian of public morals lording it over her step-daughter to the bearer of unbearable guilt and public opprobrium at the end. She rose to every occasion and gave a wonderfully moving and varied performance. The opera is worth going to just for her.
