Kool G Rap
The voice that taught a generation the mic was a weapon, a pen, and a throne all at once.
Kool G Rap (Robert Alvarez) is a Bronx-born rapper widely regarded as one of the foundational architects of East Coast hip-hop, earning the enduring title 'The Godfather of Hip-Hop' for his early mastery of complex rhyme schemes, narrative depth, and unapologetically street-level storytelling. In the context of Nas's catalog, his most iconic appearance is as a featured artist on 'If I Ruled the World (Imagine That),' the seventh track on Illmatic (1994), where his presence lends the song a generational weight that elevates Nas's youthful fantasy into something mythic.
As a collaborator, Kool G Rap represents the bridge between hip-hop's pioneering late-'80s era and the golden-age boom-bap tradition Nas helped define. His verses on Nas records are not mere guest spots; they are a lineage made audible, a reminder that the technical bar Nas was setting had already been cleared by a predecessor who treated the microphone like a laboratory.

Lore & Background
Kool G Rap emerged from the 111th Street block of the Bronx in the mid-1980s, a time when hip-hop was still finding its adult vocabulary. While peers were rapping over breakbeats with simple call-and-response structures, he was already layering internal rhymes, switching perspectives mid-verse, and building multi-bar setups that made listeners feel like they were watching a heist movie unfold in real time. His early work with DJ Polo, particularly The 5th Wave, established a template for what a solo rapper could do when the beat was treated as architecture rather than backdrop.
His membership in Rap-L, a collective that included producers and MCs who would go on to shape the East Coast sound, placed him at the epicenter of the creative network that fed into the late-'80s and early-'90s golden age. The production sensibilities that defined that era—sparse drum patterns, looping jazz and soul samples, space for the MC to breathe—carry the fingerprints of the people he worked with in those rooms. Nas, arriving a few years later, inherited that entire sonic and lyrical tradition, and the fact that Kool G Rap's verse sits on Illmatic is not a coincidence of booking; it is a passing of the torch rendered in 16 bars.
Critics and fellow MCs have long noted that Kool G Rap's influence is structural rather than stylistic. You will not find later rappers imitating his flow in a surface sense, but the expectation that a verse should tell a story, build tension, and land a conceptual punchline—that expectation was codified by him. Nas's own emphasis on narrative cohesion across an entire album, his willingness to let a track breathe, his refusal to chase hooks at the expense of content—all of it traces a line back to the Bronx kid who decided the microphone deserved the same discipline as a novelist's typewriter.
In Their Own Story
The studio is warm, the kind of warm that means the air conditioning is fighting a losing battle against July in Queens. Nas is twenty, still wearing the same flannel he wore to the session two weeks ago, and he keeps glancing at the older man in the corner who's been tapping a pen against his knee for the last twenty minutes. The beat is spinning—D'Angelo's ghost in a loop, a snare that hits like a knuckle on a table. Nas raps the hook, raps it again, raps it a third time, and the older man finally stops tapping. 'You got the dream,' he says, not unkindly. 'Now give me the world you're dreaming in.' He steps to the mic, and the room goes quiet in a way that has nothing to do with the beat. When he finishes, Nas is still. The flannel is still. The July heat doesn't matter. There is a long silence, and then Nas says, 'Okay. Let's do it again.'
Reader's Guide
The collaboration that still makes you close your eyes and go *oh, there it is*—'If I Ruled the World (Imagine That)' on Illmatic. Nas, barely twenty, paints a gilded fantasy: a palace, a throne, the whole world bowing. It's a kid's daydream set to a D'Angelo sample, and it's beautiful. Then Kool G Rap steps in, and the daydream gets a spine. His verse doesn't match Nas's youthful wonder; it *grounds* it. Where Nas is reaching up, Kool G Rap is pressing down, reminding you the throne is made of concrete and that the world you're ruling has a rent due date. The dynamic is generational without being condescending—two MCs from the same borough, separated by a few years, talking past each other and somehow saying the same thing.
What makes the pairing electric is the contrast in register. Nas's delivery on that track is smooth, almost singing, a kid who's never been told no. Kool G Rap's is clipped, declarative, a man who's been told no so many times it stopped being a sentence and became a weather pattern. You hear the Bronx in both of them, but one is the Bronx at golden hour and the other is the Bronx at 3 a.m. with the streetlights buzzing.
And the beat. God, the beat. It's so sparse there's room for both voices to exist without stepping on each other, which is exactly what you need when one MC is building a castle and the other is telling you the castle is on a fault line. It's the best 'what if' song in hip-hop, and it works because it has a 'what if' from two different decades of the same city.
You can still hear it. You always can.

- On 'If I Ruled the World,' Kool G Rap's verse is notably shorter than Nas's, yet it carries the thematic weight of the entire track—a reminder that in hip-hop, economy of language can hit harder than length.
- He is frequently cited by later-generation MCs as the primary influence on their approach to multi-syllabic rhyme construction and verse-level storytelling, placing him a full generation ahead of the technical revolution
