At age 16, Siria went to Puebla to sing with the Mariachi Metepec, but he did not get his first professional break until two years later when Julito Rodríguez and Alfredo Gil of the famous singing trio, Los Panchos, discovered him and took him to audition at CBS Records. There in 1950, he signed a contract and recorded his first album. He was singing at the same time at the Teatro Lirico in Mexico City when he met dancer Blanca Estela Saenz who would later become his wife. His first hit, "Llorarás", came two years later, and it was his then-producer Felipe Valdes Leal who gave Siria his stage name, "Javier Solís".
