The Bronx , though named for one of the boroughs of New York City, are actually from Los Angeles. There have two wildly different incarnations: as The Bronx, they are a punk/hardcore band; as Mariachi El Bronx, they are a mariachi band. This video is for one of their mariachi songs. To quote the YouTube description, “Light-up suits ahoy!”
