Swizz Beatz and Just Blaze squared off last night in the Battle of the Beats.
The friendly competition yielded a pretty big reveal; an unreleased Jay Z, Nas, Jadakiss and DMX track that Swizz dropped during the fun.
Swizz Beatz was declared the winner of the event, and its organizers promised more such showdowns including producers like Pharrell, Timbaland, The Alchemist, El-P, DJ Premier and Pete Rock.
