Well I think it's a matter of taste from here on out. Mystery School was dope, but he just sounds like a weaker version of Immortal Technique. And I agree, he has that East Coast sound to him, and I like almost nothing from the East Coast or that has that East Coast sound, specifically because the beats are repetitive to me. I don't think that better beats equals better artists, but it actually does equal a more complete sound, and in turn, a more solid track. In my opinion, of course.
You may like East Coast production though, or you may not even care, but like I said, it's a matter of taste. I also think dude just sounds boring on the mic. It sucks too, because I'm always trying to get into that sound, and it just doesn't click to me.
