Vixen was Lada Bočková, whom the Ostrava audience saw and heard already for the second time (Karolina in the opera Two Widows). Beautiful, slim and ferocious, with a clear and radiant round soprano, she gave Bystrouška above all an animal joy in life, which she defends against everyone. As Bystrouška, she was certainly a great object for the choreographer, her movement creations were very "foxish" and naturally seductive.''
''The most comprehensive performance was given by soprano Lada Bočková in the leading role of Bystrouska. She portrayed the vixen in an elemental way as a charismatic being who fights for her freedom and living space. In terms of singing, Bočková presented a self-confident and reliable concept in terms of intonation and means of expression.''
