Although they have both reached G.O.A.T. status among Hip-Hop producers, with catalogs of hits rivaled by few, at their cores, Just Blaze and Swizz Beatz are still DJs too. With nothing left to prove behind the boards, each now does it for the love. The two icons stopped by NYC’s HOT 97 in the wee hours of the morning, and decided to host an impromptu, head-to-head DJ battle.

For nearly three hours, Just and Swizzy took turns dicing up the wheels of steel. Swizz kicks things off showcasing serious turntablism skills. Just follows up, with a funky drop of Rick James’ “Super Freak,” which he chops up with the beat machine, live on the spot. Not to be outdone, Swizz bangs on the beat, too. And, that’s just the first 12 minutes…

At 25 minutes in, the warm up is over, and they take it to the next level. To the delight of onlookers like HOT’s Ebro, Just and Swizz launch into a full-scale beat battle, tweaking and freaking the tracks live on the spot. After Just drops his epic “Roc The Mic” beat by State Property, Swizz halts things for a moment, to tell the people in the room to respect what they are witnessing and turn the fuck up.

With Busta Rhymes and some of the Ruff Ryders in the room, Just continues to freak classics from his own catalog, putting unique live seasonings on some of his Roc-A-Fella classics. Swizz looks at his own catalog, with some of the very same artists, and pulls out his own cuts. Along the way, these two seasoned vets use battle DJ tricks, whether Swizz triggering the barbs from “On To The Next One,” or Just queuing up Freeway’s “Line ‘Em Up,” which is all about shuttin’ ’em down.

This continues for almost three hours in total. And, if that’s not enough, at 2:27:15, out of nowhere, Swizz Beatz premieres an unreleased song featuring Nas, Jay Z, Jadakiss and DMX. The look on Busta Rhymes’ face says it all. Unreal. At the end, both artists explain why they do this, and hopefully why more live DJ/beat battles will be taking place (as they have been for ages).

While the mood is light (but focused), both masters-at-work have some fun toasting on one another.
