 The group, composed of Carlos Almaraz, Frank E. Romero, Gilbert "Magu" Luján, and de la Rocha, was responsible for numerous murals and public art installations in the Los Angeles area.According to Luján, he and de la Rocha emphasized "indigenous and local" aspects of Chicano art, while the other two members were more interested in the European tradition.The group was also one of the first to draw mainstream attention to Chicano art, exhibiting at the Los Angeles County Museum of Art in 1974.
