The publisher of MVL wrote a book called "Cholo Style". It has lots of pics, too. It's available at Amazon. His approach is that he no longer recognizes Norte and Sur, and that it's all Aztlan. He believes Mexicans should be completely separate of white and black culture. He interviews a Sureno in prison who sounds like he's a straight up klansman with some of the shit he says. Like I said, be warned. Not everybody is going to like this dude's views.
