“Those in search of a thoroughly teutonic Fidelio should speed to The Royal Opera House, Covent Garden. It moves swiftly and surely, is powerfully cast and is conducted with fine muscular authority by Christoph von Dohnányi,” wrote The Times of this production by Adolf Dresen, which starred Gabriela Beňačková and Josef Protschka. Designed in an austere but traditional style by Margit Bardy, it conveys Beethoven's theme – the triumph of love and freedom over the forces of evil and oppression – with a natural, unadorned simplicity.
