Nah... not cause Nas couldn't use a change of pace... but because he'd be exposed.
Sorry but even tho' I think Nas is an all-time great, he has a certain pocket he has to be in. Anything outside of that and he sounds lost. It's the thing that stands as a strike against him when people call him the GOAT- he clearly has a comfort zone that always causes him to suffer when he tries to get out of it.
I don't wanna hear a Nas/Primo album either tho'. Maybe in '99 when he reeeeaaaally coulda used it, but not now.
