This Juan Epstein was epic. Rosenberg sans Ciph sat down with the legendary producer No I.D. While his friend Quartermaine standing in Rosenberg got so much history from No I.D. including the early days with Common and how they met, Big Pun stories, broke down the genius in his name and even brought us up to speed with being a mentor for Kanye West. Dope episode indeed.

Relax and Listen after the jump.
