In the annals of opera, the comprimari singers are rarely celebrated. They are the character stars from the genre: dependable singers, actually or vocally not really celebrities, but with the flexibleness and professional achievement to appear on a single stage using the Carusos, Callases, Pavarottis and Frenis in functions like Goro, Sparafucile, Baldacchi, Grimgerde, or A Nazarene. Franco Calabrese was among this kind. He worked well in Italian opera and in the 1950s participated in a few important opera tasks in smaller sized parts. These included parts in two traditional Maria Callas recordings: Tosca and Macbeth.
