Outspoken firebrands and activists Rage Against the Machine educated masses of heavy music fans by injecting their bombastic Molotov cocktail of rap, hardcore punk, funk, and metal with a sobering dose of fiercely polemical, politically charged urgency. Crashing the mainstream in 1992 with "Killing in the Name" -- their sonic protest against police brutality and systemic racism -- the band planted their flag in the scene with their triple-platinum debut, Rage Against the Machine, which courted controversy with its graphic cover of a protesting, self-immolated Buddhist monk. For the remainder of the decade, Rage continued to push this anti-authoritarian and revolutionary message, extending their platinum streak with subsequent chart-topping Grammy winners Evil Empire (1996) and The Battle of Los Angeles (1999).
