‘Testify’ is a song by American rock band Rage Against the Machine and the third single from their third album The Battle of Los Angeles.
The cover of the single was taken from the 1968 Olympics Black Power Salute. The song’s lyrics notably make reference to George Orwell’s novel 1984 through use of “The Party” slogan “Who controls the past (now), controls the future. Who controls the present (now), controls the past.”
