Late Night Pick of the Night: Mariachi El Bronx

Tonight, check out updated mariachi music from Mariachi El Bronx on Letterman at 11:35 PM on CBS. I saw these guys on one of the festival webcasts and while they wear the mariachi costumes, they are definitely not your average mariachi band that you find flitting from table to table in fancier Mexican restaurants.  They inject the mariachi with some punk attitude.
