Rodolfo Alberto Biagi was born in the Buenos Aires district of San Telmo on March 14, 1906 to Sixto & Ana Maria Gil Landaburu. At the age 13 he graduated from the Conservatory de la Prensa where he had originally studied to be a concert violinist but gradually had converted to the piano. After earning his first money accompanying the silent films (from the piano keyboard) shown at the Colon cinema he was invited by the legendary Juan "Pacho" Maglio to play in his orchestra at barely 15 years of age
