Great works are always in vogue¿ This is the case of ¿Fidelio¿, the only opera written by the deaf genius¿ ¿It represents the highest values of society: union, the fight against corruption, against evil, against the abuse of power¿, relates Pedro Halffter, musical director of the piece. However, Beethoven¿s lack of theatrical experience, in addition to the convoluted relationship between Florestan and Leonore, prevented the opera from gaining the public's attention¿ Set in Seville, the plot of love and social drama merge into a musical score that is as forceful and muscular as it is full of lyricism and passion¿
