It’s not exactly a trade secret that success in the music industry is  one part talent, many parts stage presence. To that eye-catching  effect, our favorite performers have turned transformation into an art,  keeping their fans guessing about their next single, but also about what  they’ll wear next. While some take this from the envelope-pushing to  the shocking (with Lady Gaga and her motorcycle-woman Born This Way  cover in a category all of their own), all of these artists have  challenged our senses in more ways than one.

Lady Gaga Although opinion splits somewhere between calling Lady Gaga a  visionary and a nutcase, there’s no denying the huge influence that this  Houdini has had the style world.

More shape-shifter than trendsetter, David Bowie treated  fashion like a form of performance theatre, adopting a different persona  for his various phases. From the cutting minimalism of the Thin White  Duke to the gaudy androgyny of Ziggy Stardust, each Bowie was an icon in  its own right.

The queen of one hundred (and counting) wigs, Nicki Minaj  shakes up her creative personality with almost every appearance. One of  the few singers out there with enough talent to back-up such  chameleon-like switches, Minaj performs equally well as the  scarf-wrapped Nicki Teresa as the artist formerly known as Nicki Minaj  who we all know and love.

Rather than bouncing from one look to another, Beyonce stays  loyal to her one and only alter ego, Sasha Fierce. Born from the title  album I Am … Sasha Fierce, the two different sides or the record, one  upbeat and the other soulful, allow Beyonce, as well as Sasha, to  explore multiple aspects of their creative personalities.
