Suggestions on rock n roll band/songs?

Ok I don't know if they'll help but. There's this group called Ozomatli They are a mixed ethnicity band( mexicans, whites, blacks, indians, and one Japanese guy). They sing about multiple things, one song though inpiticular, is "Violetta". it's about how the U.S. has gone to war and all of that. They were sponsored by the Govt' of the U.S. to go to the Middle East and show them that America isn't all that bad.
