Rage Against the Machine isn´t really the only metal band that matters, but their aggressive social and political activism is refreshing, especially in an age of blind (or usually self-directed) rage due to groups like Limp Bizkit, Bush, or Nine Inch Nails. Recorded in less than a month, The Battle of Los Angeles is the most focused album of the band´s career, exploding from the gate and rarely letting go the whole way through. Like a few other famous revolution-in-the-head bands (most notably Minor Threat), Rage Against the Machine has always been blessed by the fact that the band is spewing just as much vitriol as its frontman. Any potential problems created here by Zack de la Rocha´s one-note delivery and extremist polemics are smoothed over by songs and grooves that make it sound like the revolution really is here.
