Los Illegals is an American Chicano punk band from Los Angeles.
Formed in 1979 artist/muralist Willie Herrón (keyboards, vocals), civil rights activist Jesus "Xiuy" Velo (bass), drummer Bill Reyes, and guitarist brothers Manuel and Antonio "Tony" Valdez (who also perform with their Mariachi parents & relatives). They were one of the early framers of U.S. Roc en Espanol in the early 1980s.
The Smithsonian Institution exhibition, American Sabor, called Los Illegals "one of the most important East L.A. bands of the 1980s".
