He is especially known for his heartfelt voice and his ballads. He rose to stardom in 2001, when he appeared as a guest on a hit TV show in Spain. Alex started to tour national radios with his guitar to sing his songs live and be interviewed. Eventually this strategy worked and his album finally hit the charts. But he reached absolute fame with the publication of the song "Sin Miedo A Nada", featuring Amaia Montero, his biggest hit to date.
