Louis Frausto Pérez, Jr. (born January 29, 1953) is an American songwriter, percussionist and guitarist for Los Lobos[1] and Latin Playboys.

[2] Pérez started with Los Lobos playing primarily jarana (a small Mexican guitar) and singing.

As Los Lobos ventured into Norteño music and rock, Pérez became the drummer, first with just a snare drum.

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.

He also paints in his free time and has been the art director and artistic supervisor on many of Los Lobos' albums.
