Long before we even watched the video for "Berzerk," you knew the visual direction Em was going in. The cover art for the single is similar to LL Cool J's album cover for Radio, which dropped in 1985—and was also produced by Rick Rubin. Em's always been a big fan of LL. Five years ago, he pranked him on Shade 45 by calling in during a radio interview pretending to be just an everyday fan.
