The two later made up. Yet in the UK, tales of aggression are rare in the rap scene, says Andy Cowan, editor of Hip-Hop Connection magazine. I cannot think of any occasions where there's been any trouble with guns at a show. I think part of that is just because of our stricter gun laws. Rather than being a rogue element of the American rap scene, some commentators have lambasted record companies for seizing on violence as a marketing ploy.
Aggression plays up to the white middle-class image of urban black life, they say.
The record industry make a living off it in much the same way that boxing promoters did in the past - as a way of exploiting young black men and women seeking a path out of the ghetto. This alleged white exploitation of black culture has been cited as one possible reason for the attack on Westwood, who is the white son of a church minister. Whatever the true motive behind the attack, Westwood at least is resigned to the violent nature of the business. There will always be conflict.
