Gangstarr hasn't sold out and never will. And while your speaking about flow, Guru has probably the best flow I've ever heard. I mean the guy doesn't even have to rhyme to have good flow, he just has the voice for it, you can tell from any song of his that he has some of the smoothest lyrics out there. Don't compare him to people like Nas and Jay Z, Gangstarr is in a leauge all their own, i'm not saying there better or worse then people like jay z and nas who definitely have skills, but there is no doubt that gangstarr is full of talent.
It's all about the East.
