“Monster” is the fourth single off Eminem’s successful MMPL2 following “Berzerk,” “Survival,” and “Rap God.” Featured artist Rihanna joins Em in a trippy therapy session for the “Monster” music video directed by Rich Lee. The clip is quite cool, actually; Em borrows from Chris Nolan’s Inception and takes a trip down memory lane as he rides down a mysterious elevator that calls back and even recreates music videos of the past and many high points from the rapper’s long career (remember when he performed with Elton John at the Grammys in 2001?). Hit play and relive it.
