In eighteenth-century Spain, Leonore's husband Florestan has been arrested and imprisoned by his villainous noble rival Don Pizzaro, for attempting to expose the latter's crimes. Determined to rescue him, Leonore disguises herself as a boy, Fidelio, and takes a job at the prison where he is being held. Out of that simple synopsis, a great work of art emerges, with Beethoven's Fidelio presented on Monday 24 July by singer and teacher, Dr. Wendy Dixon who has sung the role of Leonore for Opera Australia.
