Siria began singing in competitions under the pseudonym of "Javier Luquín" in which the winner would be awarded a new pair of shoes; he was eventually banned from participating because he so dominated the competition. At that time he was working as a butcher, and sang while he worked. His boss, David Lara Ríos, heard him and was so impressed with his talent that he urged Siria to dedicate himself to his music and recommended him to a voice coach, even paying for singing lessons with Noé Quintero.
