Episode Three: Mexican-Americans in CA, TX and across the Southwest create their own distinct musical voices during the second half of the 20th century. Their music would play an important role in the struggle for Chicano civil rights and ultimately propel them from the barrio to the national stage. Episode Four: Focuses on the Latin Pop explosion of the turn of the century and the success of artists like Ricky Martin, Gloria Estefan and Shakira in the English-language market. As studios concentrate on star-driven Pop, Latino youth gravitate toward urban fusions - Spanish Rap and Reggaeton, as well as Rock en Espanol.
