All this proves is Nas is a TRUE student of the game and got alot of musical influence from his pops.
I was mind blown when I saw them years ago. Honestly, I thought it was creative how Nas incorporated those ideas into his concept of growth in the QB projects. It was crazy how he carried the concept across those four albums and then unveiled it in a Source ad for Nastradamus. When I saw the ad and then the caption of "from boy to man to king to prophet", I was legit .
