I remember my friend lending me his Toxicity CD when my dad dropped him off, listening to it in the car on the way home, and having my mind blown. Besides being the most aggressive music I'd ever heard, it was my first exposure to overtly political music; the album opens with Prison Song, which dispenses with any sort of metaphor and is a straight-up polemic, introducing me to the effects of the drug war and CIA drug trafficking and regime change.
