This documentary tells the story of generations of young Mexican-Americans who proudly expressed their identity through music. Narrated by Edward James Olmos, the program is filled with intimate first-person storytelling, rare film and photos, and exuberant music from artists such as Lalo Guerrero, the Father of Chicano Music; the legendary Ritchie Valens; and classic bands such as Cannibal and the Headhunters, who toured with the Beatles, Thee Midniters of "Whittier Blvd." fame, El Chicano, Tierra and perhaps the greatest of them all, Los Lobos.
