Francisco Fiorentino was tango musician, singer and director of the guardia nueva. He is famous for his work as a singer with the orchestra of Anibal Troilo and regarded as the first cantor de orquestra, the tipical singer of the golden age of tango.
Born in San Telmo in 1905 to a family of Italian immigrants, Francisco Fiorentino studied music at the conservatory of Minotto Di Cicco. In his youth he used to play with his older brother Vicente in the cafes and theaters of Buenos Aires for a living.
When he joined the orchestra of Francisco Canaro in 1924, Francisco Fiorentino wanted to sing. These were the years when Canaro was experimenting with estribillistas, however Canaro did not think much of Fiorentino as a singer back then. This is why Fiorentino left to work with other orchestras such as those of Juan Carlos Cobián, Juan D’Arienzo, Angel d’Agostino, Pedro Maffia and the Orquesta típica Victor, acting both as a musician and estribillista.
The estribillista used to sing only the refrain and were not usually considered as members of the orchestra.
When Fiorentino joined the orchestra of Anibal Troilo on July 1st 1937 he became the first orchestra singer. Together Troilo and Fiorentino recorded 62 tracks including “Yo soy el tango”, “Tinta roja”, “Fueye”, “Barrio de tango”, “Los mareados”, “Gricel” Garua, and “El bulín de la calle Ayacucho”. Their innovative collaboration also resulted in giving a second life to tango poetry and singing which was in need for new channels following the death of Carlos Gardel in 1935.
According to Blaya  Francisco Fiorentino was not technically a great singer. His voice and diction had certain limitations but he was good at conveying the emotion.
In 1944, Francisco Fiorentino leaves the orchestra of Troilo. He works with Orlando Goñi for a while and forms his own orchestra with Astor Piazzolla. In 1948 he joined the orchestra of José Basso. He made many good recordings including 22 with Astor Piazzolla but never reached the same success as he did in while working with Troilo.
In the 1950’s Francisco Fiorentino began traveling to Uruguay and to the interior of Argentina to perform. He died in a car accident in 1955 near Mendoza.
