There are two undercurrents in Chicano rock. One is a devotion to the original rhythm and blues roots of Rock and roll including Ritchie Valens, Sunny and the Sunglows, and ? and the Mysterians. Groups inspired by this include Sir Douglas Quintet, Thee Midniters, Los Lobos, War, Tierra, and El Chicano, and, of course, the Chicano Blues Man himself, the late Randy Garribay. The second theme is the openness to Latin American sounds and influences. Trini Lopez, Santana, Malo, Azteca, Toro, Ozomatli and other Chicano Latin rock groups follow this approach. Chicano rock crossed paths of other Latin rock genres (Rock en español) by Cubans, Puerto Ricans, such as Joe Bataan and Ralphi Pagan and South America (Nueva canción). Rock band The Mars Volta combines elements of progressive rock with traditional Mexican folk music and Latin rhythms along with Cedric Bixler-Zavala's Spanglish lyrics.
