There is a LA based "punk" band named Mariachi El Bronx. When I find out what their connection is to the Bronx I will let you know. Until then, please enjoy the clip of the band performing on Jimmy Kimmel the other night. Anyone who views the video will see they are an interesting mix of punk and I would call "Central American Style music". If anyone knows what the fusion style of music is called, please do let us know.
