Well when you said the MC Blacked out I assumed you meant the guy who's album it was not a guest MC. I still think the point stands because Biz wasn't that kind of MC. Lots of my favorite MC's aren't. Jeru didn't on The Sun Rises In The East. Doug E Fresh isn't someone I would ever describe as blacking out on a track. Chuck D, Q Tip or Paris either unless you are expanding your definition of Blacking out to be extremely wide. I take Blacking out to mean an MC just going for his showing that no one can fuck with him (or her) on the mic on some straight I'm better than you type shit. I don't think you have to be in that lane to be Hip Hop or make a great rap album.
