Elvis Presley is rock 'n' roll. He sang like a dream, he was sexy enough to send girls swooning, and he exuded enough cool not to have the boys resent him. Adults worried about his rebellious nature, but they were eventually comforted by his polite, courteous manner. Yet as perfect as Presley's 1950s rock recordings are, he excelled at so much: down-home country crooning, raucous R&B belting, enraptured Gospel singing, and classic pop balladeering. Elvis wasn't a vocal chameleon: these styles seeped out of him naturally, allowing his own personality to shine through. Despite his high level of talent and achievement in his craft, it was Elvis who made rock 'n' roll the international language of pop and inspired countless kids around the world to pick up a guitar or step up to a microphone. That said, Elvis didn't have a faultless career: he starred in plenty of bad movies, sang dozens of lame songs, got fat, and wore a kitschy white suit. But so what? He forever changed pop music, recording acres of perfect material over two short decades. Elvis (deservedly) remains the King.
