They came. They saw. They put on an epic show. As promised, super producers Just Blaze and Swizz Beatz battled it out last night (Feb. 24), in an event dubbed Battle of the Beats. And they did not disappoint.

According to the rules, which the beat-making vets made up the day prior when they announced the battle, both men only got to use a kick, snare and hi-hat in this special contest. They also flipped classic tracks from their illustrious careers. The beat battle was live-streamed on Instagram and hosted by Hot 97's Ebro Darden. Busta Rhymes and Cassidy were among those in attendance.

The production gawds went back and forth, putting on some ill creations for the packed crowd of onlookers, as minutes turned into an hour-plus of entertainment. As time closed out, Swizzy dropped a bomb by unveiling a previously unreleased track featuring Jay Z, Nas, Jadakiss and DMX (1:46:00-mark). There is no word on what project the song is to appear on. There is a chance it could end up on The Monster's solo project.

In the end, Swizz was announced the winner of the friendly competition. The duo also expressed wanting to do follow-up events with other ill producers match-ups such as Pharrell vs. Timbaland, The Alchemist vs. El-P and DJ Premier vs. Pete Rock.
