A sell-out is a person who is wack, and then tries to be different to hide that fact. That's a guy like Justin Warfield . You know the guy who claimed he was on LSD and used all acid-jazz stuff, when really he had weakest flow in years. Same thing with Kwame , the polka-kid, he was weak and now he's gone. However all the artists who came after him with the live-jazz are really just using it as a gimmick.
Jazz is just one gimmick.
Wearing stupid cloths. Using words like iggedy in every sentence, or rhyming in spanglish. All these things will be fully accepted if only you're a dope rhyme sayer. The Fu-gees will be accused of selling out because they sing. For God's sake just look at Bone-frogs N harmony , PMD , Da Brat , and all of those RnB rappers.
