Jay-Z and spent years as embittered rivals, trading Titianesque blows in , only to bury the hatchet in 2005 during Jay’s “I Declare War” tour. Since then the pair moguls have linked up on a variety tracks, including “Black Republicans” in 2006, “Success” in 2007, and “BBC” in 2013. Dedicated fans know there’s still one that got away, a -produced banger called “The Scientist,” which first surfaced back in 2009 — a timeline that places Nas firmly in Untitled territory.

Though the Jay-Z-assisted track never arrived in full (for reasons unknown), a snippet Hov’s verse recently surfaced. Over a nostalgic  Just Blaze produced instrumental, itself a reminder a lost era, Jay sounds comfortably in his mafioso bag. “Hovito Brigante, my own people that got me, that’s what I get for snoozin’, moving too sloppy,” he spits. “I’m back brilliant, my brains is back in the building, the lights back on the fridge you dig?” 

The news came as a surprise to Nas die-hards, many whom heard snippets “The Scientist” from a while back and assumed it was a solo joint. Though some speculate the track was meant for The Lost Tapes 2, others seem to think it’s destined to arrive in full at one point or another, especially with news both a Hov-heavy album and a new project from Escobar himself. While we can’t post the snippet on this page, you can check it out YouTube or right here.
