If "heavy metal" was the Anglo-American contribution to low culture, then "rap" was the African-American donation. And if "metal" came from the garage where Junior had been sent with his guitar and extension cord, then rap came from the street where young blacks played the only instruments they could afford—the mouth organ and the foot drum. Rap is performed in street clothes; metal in elaborate costumes of leather and fringe. In metal, the volume carries the aggression; in rap it is the words. Both are rife with adolescent misogyny, homophobia, and threats of violence. They are rude, bawdy, boastful, with a kind of "in your face" aggression (called "attitude") characteristic of insecure masculinity. Both musical forms were unique, however, in that they produced platinum records with little radio exposure. They found their audience on MTV.
