Chicano rave culture in southern California provided a space for Chicanos to partially escape criminalization in the 1990s. Artist and archivist Guadalupe Rosales states that "a lot of teenagers were being criminalised or profiled as criminals or gangsters, so the party scene gave access for people to escape that." Numerous party crews, such as Aztek Nation, organized events and parties would frequently take place in neighborhood backyards, particularly in East and South Los Angeles, the surrounding valleys, and Orange County. By 1995, it was estimated that over 500 party crews were in existence. They laid the foundations for "an influential but oft-overlooked Latin dance subculture that offered community for Chicano ravers, queer folk, and other marginalized youth." Ravers used map points techniques to derail police raids. Rosales states that a shift occurred around the late 1990s and increasing violence effected the Chicano party scene.
