Genius. Pure genius. Way before Rage Against the Machine, before Run-DMC's collaboration with Aerosmith and before their infamous collaboration with Public Enemy, Anthrax take the credit -- or blame -- for being the pioneers of merging rap and metal. Released in 1987, their now-classic I'm the Man is a funny tribute/parody/attempt at hip-hop that is not only pulled off successfully, but it's also the first release that showcases Anthrax's sense of humor.
