Most rappers open their solo debut trying to prove they can rap. Mos Def opened his by talking.
October 12, 1999. Twenty-seven years ago today.
Hip-hop was approaching a new millennium. Eminem had exploded onto the scene with The Slim Shady LP. The Roots had delivered Things Fall Apart. Lauryn Hill was still riding the extraordinary success of The Miseducation of Lauryn Hill.
And over at Rawkus Records, something special was taking shape.
Just one year earlier, Mos Def and Talib Kweli had introduced Black Star to the world. Their chemistry, lyricism, and unmistakable Brooklyn identity had helped make Rawkus one of the most talked-about labels in underground hip-hop.
Now Mos Def was stepping out on his own.
But instead of opening his debut with an explosive verse, he began Black on Both Sides with “Fear Not of Man,” reflecting on fear, community, and the state of the culture before settling into the kind of rhyming people already knew he was capable of.
It was an unusual introduction. And a pretty good indication that this wasn't going to be an ordinary rap album.
Behind the scenes, the recording sessions brought together an incredible collection of talent.
Diamond D supplied the production for “Hip Hop.” DJ Premier delivered that unmistakable sound on “Mathematics.” Ayatollah flipped Aretha Franklin's “One Step Ahead” into the unforgettable foundation of “Ms. Fat Booty.”
88-Keys, Ali Shaheed Muhammad, Psycho Les of The Beatnuts, and others contributed to an album that moved effortlessly between gritty New York production, jazz, soul, and live instrumentation.
Busta Rhymes, Talib Kweli, Q-Tip, and Vinia Mojica added their own contributions.
And Mos Def wasn't content simply to rap over what everybody brought him.
He wanted to explore.
“Ms. Fat Booty” unfolded like a little movie, full of character and detail. “Mathematics” turned social realities into a devastating lyrical exercise. “New World Water” examined the politics of something most people took for granted.
Then came “UMI Says.”
No lyrical acrobatics. No elaborate displays of technical superiority. Just a man singing with remarkable openness and vulnerability.
For an artist already respected as an exceptional MC, it was another side of Mos Def that some listeners hadn't expected.
And here's a fascinating little piece of the album's history.
Engineer John Wydrycs later recalled that when he began working on the project, some of the tapes still had “Black Star” written on them. He believed Mos had carried over ideas that hadn't made it onto the duo's album.
Meanwhile, the studio environment was something of a gathering place. Musicians, producers, friends, and collaborators came through, exchanging ideas while Mos worked to bring his vision together.
What emerged wasn't simply a collection of songs.
It was a portrait of an artist who understood where hip-hop had come from, loved the neighborhood that shaped him, and wasn't afraid to explore where the music might go next.
Twenty-seven years later, Black on Both Sides still rewards a front-to-back listen.
You can hear the hard drums, the soul samples, the political concerns, the love for Brooklyn, and the willingness to be vulnerable—all coming from the same artist.
Maybe that's what made it special.
Mos Def didn't have to choose between being a lyricist, a storyteller, a singer, or a student of the culture.
He could be all of them.
And he made an album that gave every one of those sides room to breathe.
For those who were there in 1999, what was the record that pulled you into this album? Was it “Ms. Fat Booty,” “Mathematics,” “UMI Says,” or something deeper in the tracklist?
27 years of Black on Both Sides. Respect to Mos Def, now known as Yasiin Bey, and everyone who helped bring this remarkable record to life.
And with that said, I think I know exactly what I'm doing next.
I'm heading back to my room, putting on Black on Both Sides, and listening to the whole damn thing, front to back.
Some records just deserve that kind of attention.
