Just listen to anything from Guru/Gang Starr. Guru da GAWD.
And of course, NaS drops heat too.
"A Mastermind
Sees it coming before it comes
A Mastermind
Before he go to war he counts his one
A Mastermind
Everything planned out perfect
In case y'all nikkaz got to get murdered
A Mastermind
Sleeps at night, real easy
A Mastermind
'Cause everything he does is by the book
A Mastermind
Never do a thing irrational
Lives forever, these tales are classical"
