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, former bandoneonista in the orchestra of Francisco Canaro. His older brother Vicente was also a musician and together, in their youth, they played in the cafes and theaters of Buenos Aires for a living.
Francisco Fiorentino was a talented musician and in 1924 he joined the orchestras of Francisco Canaro. These were the years when Canaro first incorporated singers into his orchestra and Fiorentino wanted to sing but Canaro did not think much of him as an estribillista at that time and Fiorentino went on working with other orchestras both as a bandoneonsita and estribillista in many ochestras including those of Juan Carlos Cobián, Juan D’Arienzo, Angel d’Agostino, Pedro Maffia and La típica Victor.
In the 1930’s Fiorentino he also worked as a solist and performed with Los Poetas del Tango.
Francisco Fiorentino may not have been the very first singer to perform with an orchestra. Other signers who worked with orchestras in those early year are Charlo and Roberto Díaz. However he was first to record a full song, “Serenata de amor” with the orchestra of Roberto Zerrillo, and more importantly he was first to fully integrate an ochestra tipica as a singer.
Fiorentino made his debut with Anibal Troilo on July 1st 1937. Together Troilo and Fiorentino recorded 62 tracks including “Yo soy el tango”, “Tinta roja”, “Fueye”, “Barrio de tango”, “Los mareados”, “Gricel” Garua, y “El bulín de la calle Ayacucho” and gave a second life to tango poetry and singing which was in need for new inspiration following the death of Carlos Gardel.
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 ochestra of Troilo. He works with Orlando Goñi for a while and forms his own orchestra with Astor Piazzolla. In 1948 he joined the ochestra of José Basso. He made many good recordings including 22 with Astor Piazzolla but never reached the same had with Troilo.
In the 1950,s he began traveling to Uruguay and interior of Argentina to perform. He died in a car accident in 1955 near Mendoza.
