His fame as good singer gave origin to his first contract to record discs for the Victor company between 1911 and 1912. They are ten folk numbers.
A couple of years later, he recorded his voice for ERA discs.
Later came the stage of his artistic association with Carlos Gardel, from which would result the famous Gardel-Razzano duo.
José Razzano had a splendid tenor voice, of perfect intonation, that blended perfectly with Gardel's range.
They worked intensively. They traveled to Uruguay, Brazil, Chile and Spain until, reaching 1925, Razzano, with his vocal cords seriously damaged, gave up singing.
