4. David Bowie
Glam rock reared its flamboyant head in the early 1970s, and David Bowie was the vanguard of this movement that filled the void after the Beatles' break-up in 1970. He found immediate success while wearing insane outfits that adorned the glam character Ziggy Stardust - a rock 'n roll star from outer space. Even though glam rock and its frontman Ziggy were both huge successes, Bowie ditched the make-up and the glitter in both style and sound, and transformed himself with slick British tailored suiting. Bowie would continue to re-conceive both his sound and his manner of dress, but the '70s were the decade he went from one extreme to the other without missing a beat.
