Sia

Although raised in Australia, Sia Furler rose to fame after moving to the U.K., where she worked as a guest vocalist for several groups -- including the electronica duo Zero 7 -- and released her own solo albums. Born in 1975, she first performed on the Adelaide jazz circuit during the '90s as a vocalist for the band Crisp. An attempt to launch a solo career in 1997 didn't pan out, though, and the blonde, blue-eyed antipodean eventually hopped on a plane to London. While there, she landed a gig as a backup singer for Jamiroquai and inked a solo contract with DancePool, a sublabel of Sony.
