The Swiss photographer Andres Herren, who started when he was 14 decided to venture to LA and document the Chicano culture. With a little help and tutelage from fellow photographer Estevan Oriol, he was welcomed at family reunions and social gatherings that allowed him to capture an insider's perspective of the LA Chicano culture. Unfortunately I can't find the video on youtube, but here is a link to the video on
