From BBC: Narco Corridos. An interesting article on the music aspect of the smuggler/drug/gang culture of Mexico and the US.
It has been a bit of a culture shock down here for me in this aspect. You see guys drive by in pimped out cars with big stereos blasting music. But the music is not rap or metal, as a gringo like me would expect. To the northern ear, it sounds like a mix between speed folk and polka. Most is a bit too amped for me, but I like Virtuoso Mariachi – a sort of classical approach to mariachi music.
