Hip hop uber-producer (and Crate Diggers alum!) Just Blaze is known to many for his work with Jay-Z, Dr. Dre and countless other rappers. But fans of the producer know he gets as deep into his house music as rap production, frequently DJing all-house sets and promoting his favorite dance music tracks on his Twitter. In advance of both an upcoming EP for Fool's Gold and tour with EDM wunderkind Baauer, Blaze drops "Exhibit J," flipping a piano riff off his own production of Jay Electronica's "Exhibit C" into dance music bliss.
