Just after completing her studies at the Milan Conservatory, she made her debut in 1822 at La Scala, as Emerico in the première of Mercadante's Adele ed Emerico. The opera obtained a good success and this facilitated the career of Isabella Fabbrica, which in the same year interpreted other premières of operas of Donizetti (Chiara e Serafina) and Mercadante (Amleto).
After a few years spent mainly between Milan and Turin, she married, after dropping a possible union with Mercadante,[1] the tenor Giovanni Battista Montresor, son of the contralto Adelaide Malanotte.
After her debut in Rome in 1830, she spent some years in Portugal, where she obtained an extraordinary success.[2] Later Fabbrica sang also in Madrid and Saint Petersburg, until 1850, when she ceased her activity.
Isabella Fabbrica was very famous for her talents as an actress and for her powerful voice.[3]
^Regli wrote in its Dizionario biografico: "She was beloved in all theaters where she sang, but in Lisbon she became an idol. Here she received unceasing handclaps and delighted the audience with her noble manners and her fine style." ("Se fu l'amore di tutti i Teatri che calcò, fu l'idolo di Lisbona, ove non cessavasi di applaudire e di gustare gli eletti suoi modi e il puro suo stile")
