He made his La Scala debut in 1953, in a contemporary work Leonore 40/45 by Rolf Liebermann, and took part in the premiere of the Dialogues of the Carmelites in 1957.
In 1954 he starred in the role of Pinkerton in the film adaptation of Madama Butterfly directed by Carmine Gallone and shot on location in Italy.
According to the information regarding this film version, although Filacurudi acted the role of Pinkerton, it was actually sung by another Italian tenor, Giuseppe Campora.
His last appearances on that year were at a production of Carmen of the Elizabethan Theatre Trust Opera Company and later in New Zealand where he interpreted again the character of Pinkerton in Madama Butterfly.
Filacuridi sang a wide range of roles in operas such as; Rigoletto, Un ballo in maschera, La bohème, Tosca, Les contes d'Hoffmann, Louise, Werther, Idomeneo, and Lohengrin.
