Brehs.......listen to me when I say this.
Black Thought is Mensa-status when it comes to rapping. He's a fukking rap savant and I dare you to say he isn't.
This dude had at LEAST ten minutes worth of errant bars READY at the drop of a fedora in one take. No easing into it. No beating around the bush. IMMEDIATELY.
Think about HOW many fukking verses he must have in his head from writing for the albums. He did THAT in one...TAKE.
Black's been doing this shyt for so long, that I wouldn't be surprised if he has verses that he's written in his head that he's never spit out loud, but could call upon whenever.
