Pop's new voices of rage

THERE WAS a time, not so long ago, when rebellious rockers took on the establishment. Crosby, Stills, Nash & Young railed against Richard Nixon's America in 'Ohio'; the Sex Pistols savaged Margaret Thatcher's Britain in 'Anarchy in the UK'. Gil Scott-Heron zapped Ronald "Ray-Gun"; Linton-Kwesi Johnson rapped against political thuggery. Scads of artists, black and white, rallied behind an antiapartheid anthem called 'Sun City'. There was righteousness in the rage: angry, disenfranchised voices attacking power structures.
