Few bands have packaged themselves as brilliantly as the Strokes on their debut. Before Is This It even came out, New York's mod ragamuffins were overnight sensations, jumping from Avenue A to press hysteria and the inevitable backlash, all inside a year. Julian Casablancas, guitarists Nick Valensi and Albert Hammond Jr., bassist Nikolai Fraiture and drummer Fabrizio Moretti were primed for star time, updating the propulsion of the Velvet Underground and the jangle of Seventies punk with Casablancas' acidic dispatches from last night's wreckage. They inspired a ragged revolt in Britain, led by the Libertines and Arctic Monkeys, and reverberated back home with the Kings of Leon. And for the bristling half-hour of Is This It, New York's shadows sounded vicious and exciting again.
