When you are a proud music geek, you sit and think about things like who is the ultimate rock star. There are a number of choices for a variety of reasons. For global impact it could very easily be Bob Marley. Elvis Presley was of course the first real rock star (not that he originated rock, but the first true rock star). With their mystique and charisma Jimi Hendrix and Jim Morrison have enthralled fans for generations. Mick Jagger and Keith Richards have embodied rock and roll for decades. When it comes to the idea of rock gods no one surpasses Robert Plant and Jimmy Page.
Then when you look at all the traits that define a rock star -- the talent that transcends generations; an uncompromising approach to their art; a voice for good; influence on other musicians; a willingness to evolve and a charisma that speaks to all languages and all cultures -- you could make a damn strong case for David Bowie, who might be number two.
