After Mos' Def with Talib Kweli together published the exorbitant fats album "Black Star", was already clear that it would someday have a possible solo album by him extremely difficult to keep the restrictions imposed by his own standard. But this masterpiece is in my opinion, new standards. From start to finish is not a bit bored on the contrary, each work really bubble over with creativity and diversity, whether it be the aggressive song "Do It Now" with Flipmode Squad Representaa Busta Rhymes ("black and proud"), or "Climb "featuring Vinjja Monica, an absolutely chilliges quiet song. Man can simply highlight no single work, or opt for no favorite track, because nearly everything was produced superb, not least in advance as a 12 "released single" Mathematics ", in once again Primo, DJ Premier of Gang Starr, his magic Finger had the game Typically Primo -. Style the beats come along with loops, the chorus is backed by Erykah Badu and Fat Joe Scratches ("..it's simple mathematics .. i revolve around science .... do your math .. "through which The Mighty Mos' his rape placed. Those who thought at first, a solo album of a half Blackstar without the missing could be due to the slightly varied voice of Mos Def slightly boring will be disappointed. Mos Def shows here all his Skillz , and plenty of it. As expected, comes the textual aspect not too short, of course, he represents as often as possible, the thesis 'Stay Black' which like a red thread through the album and maybe a little for some hypersensitive White makes more difficult to access. One quickly realizes that someone comes here busy with his environment "..Young bloods can not spell But They Could rock you in PlayStation This new math is whippin motherfuckers ass You wanna know how to rhyme you better learn how to add .." what has often earned him the reputation of Political Rappers. For me the best album that was released in 1999 !!!
