From Murder Dog Magazine, interview with Paul Wall.
I think a lot of people were surprised when you broke up. Nobody really expected that shit
"Yeah, me and Chamillion, cause we grew up together and I think we kind of blew up bigger and faster than we expected. Our personalities just changed and we just grew up and grew apart. It was to a point where we was just clashing head on. And it was little stuff. When you around somebody every single day of your life there's bound to be some problems coming in. Like a lot of little things happened here and there and a straw don't weigh nothing, but if you get enough straws together somebody's camel's back might break. That's jus what it was. It was to a point where we were mixing business with pleasure and it went to a point where we weren't gonna be friends no more, that's cool we don't have to be friends, but we're still gonna make money together. That's what people say now, you can still make money together, but they don't understand. Back when we were doing that, that's how it was back then. Then it started getting so bad, from my viewpoint I was like damn the business not right, I'm not making no money and we're not friends. The only reason I stayed around was because I gave it everything I had and just stuck with it just because of our history together growing up together."
And then some shit about their contract but doesn't deal with their relationship.
