Pérez started with Los Lobos playing primarily jarana (a small Mexican guitar) and singing. He is one of the founding members of Los Lobos, established in 1973. As Los Lobos ventured into Norteño music and rock, Pérez became the drummer, first with just a snare drum. In 1990, Victor Bisetti was hired to be a combination drum tech, drum coach and percussionist. As time went on, Bisetti took a more active role as drummer, allowing Pérez to move back to the front of the stage and start playing guitar. Bisetti was replaced in 2003 by Ruben (Cougar) Estrada. Estrada was replaced by Enrique "Bugs" Gonzalez in 2013.
