"Mariachi El Bronx cover The Decemberists"

When the guys in the rollicking punk outfit The Bronx decided to stretch out musically, they didn't just add some new instruments or gradually shift styles: They created an alternate band and embraced Mariachi El Bronx, and immersed themselves in the traditional Mexican music. (Yes, they even wear charros.) Because they're so associated with their hometown of L.A., the band leaped at The Decemberists' "Los Angeles, I'm Yours," a funny little love letter to the city. Enjoy, and buenos dias.
