Asco was an East Los Angeles based Chicano artist collective, active from 1972 to 1987. Asco adopted its name as a collective in1973, making a direct reference to the word’s significance in Spanish ("asco"), which is disgust or repulsion. Asco’s work throughout 1970s and 1980s responded specifically to socioeconomic and political problems surrounding the Chicano community in the United States, as well the Vietnam War. Harry Gamboa, Jr., Glugio "Gronk" Nicandro, Willie Herrón and Patssi Valdez form the core members of the group.
