3. Radiohead, 'OK Computer'
Progress is a bitch, but don't let the machines, or their masters, grind you down: That is the simple message encoded in the art-rock razzle-dazzle of OK Computer. Hailed as The Dark Side of the Moon for the Information Age, Computer is too brittle in its time-signature twists and hairpin guitar turns, too claustrophobic in mood, to qualify as space rock. Instead, Radiohead shatter the soul-sucking echo of isolation and enforced routine with the violent mood swings of "Paranoid Android" and Thom Yorke's arcing vocal anguish in the gaunt, yearning ballads "Let Down" and "Lucky." Somehow, OK Computer went platinum a year after its release — a welcome testament that smart still sells.
