This right here.
Ras Kass spoke about this before. A lot of dudes got inspired by what was going on in the underground in the mid-90's, and started emulating what was being done around that time, with all the lyrical gymnastics and all that. But there aren't many dudes who can do that and actually say something in a way that hasn't been said a million times before by more superior underground MC's. At a certain point, it's going to come down to songs and albums, and they typically don’t have the catalogues that really stand out. I remember Scarface saying he hears a lot of cats saying shyt like, "the lyrical individual, who is mystical and spiritual, and a miracle". He said, 'They rhyme all that shyt and didn't make anyone feel anything." And he's right, lol.
Being a technical MC is more than structure and just making a bunch of shyt rhyme. That's the easy way out. You not only have to do that, but you also have to throw personality and humor, storytelling, style, emotion, etc., on the table. When you're able to do all that, then you're ready to be mentioned with the greats. Speaking of Kass, what he did on Soul on Ice is a perfect example. That was masterful. Sean Price and Pun, G Rap, Monch, Black Thought. Lupe is definitely another one. There are a lot of dudes that have done it and dropped classics. But I've never considered Elzhi to be in that class with those dudes. I like some of his shyt, but never heard anything from him that I was super impressed with.
