Mauricio Aznar Müller (January 26, 1964 – October 2, 2000) was an Aragonese poet and musician, leader of the bands Golden Zippers, Más Birras and Almagato. Some of his songs, like «Apuesta por el rock and roll», popularized by Héroes del Silencio, have become part of the cultural heritage of rock made in Aragon. His career begins with the founding of the group Golden Zippers in the 1980s, a rocker style (large toupees in James Dean style) and rockabilly music group. In 1983 he recorded a single with the Cara 2 label, which contained three songs.
