Nas is Def Jam. No ID is Def Jam. It would stand to make sense that if Nas were to go with ONE producer for his next album it would be Dion. Dion has had major experience being the sole producer for an entire album (I.e. some of Common's best work) and the beats he had on LIG were universally praised as some of the best production Nas has ever utilized. I personally wouldn't be upset if Nas and Salaam hooked up for an entire album as some of Nas's best work has come out of their collaborations, but I honestly think that ANY early Nas news right now is too premature. Nas has always been NOTORIOUS for speaking on the early shaping of his albums only for the completed project to be ENTIRELY different.
Remember when he was gonna do the NASdaq Dow Jones album supposedly having a 50 Cent diss? That album eventually became Hip Hop Is Dead...
Remember when for the ****** album he was gonna work with Jermaine Dupri, DJ Khaled, and The Hit-Men? That album ended up with production by NONE of those people
Remember when he was supposedly working with Alex Kidd, Kane Beatz, and Bangledesh for LIG and half the posters on this VERY thread were crying foul? That album of course ended up with No ID and Salaam being the bulk producers...
So right about now its too early to tell, he's still in the early conceptual phase, its still probably a little murky that he'll even drop it this year....
But WHATEVER he does, WHOMEVER he works with, and WHENEVER it drops, I'm expecting greatness
