This act is described as a mariachi band. I don't think you can hear that at all in this song. Sure, it has horns. There are some small hints of Latin sound in some of the melodies. Beyond that, though, this is a powerhouse alternative rocker that just oozes cool. I am absolutely in love with this cut and hope to hear more from this act.
