About the judge

The discography of Grammy Award winning producer Rockwilder runs deep. Very deep. After his early work in the golden year of 1994 for Organized Konfusion, Redman and Erick Sermon, he went on to make beats for the likes of De La Soul, LL Cool J, Busta Rhymes, Jay-Z, Big Pun, D.I.T.C., Prodigy (R.I.P.), Nas, and many other notable artists—ranging from hip-hop to pop.

He’s affiliated to the Def Squad crew of Erick Sermon, Keith Murray, and his childhood friend Redman and usually work from the classic Def Squad Studio in Long Island. Twenty-five years and counting, still rocking wild. Case in point: watch how he flips "Opinions of History (Shi Guan)" by Xu Peidong in his Rhythm Roulette episode.
