10. Rihanna (2008)
When Rihanna debuted new single "Disturbia," the performance was straight-up good girl gone undead. A horde of zombie dancers with glowing yellow batons led the way as goth-styled Ri-Ri rolled out to the stage on a towering pyramid enveloping her lower half. Intro-ed with the synth riff from Eurythmics' "Sweet Dreams," and later interrupted with a scorching interlude from the White Stripes' "Seven Nation Army," this frenetic performance made a rock star out of Rihanna. For a song about going crazy, she was clear-headed and in control the entire time.
