We Are Born

Although celebrated for her work with Zero 7, Sia chose to focus on her own career in 2009, leaving the electronica duo to hire a new singer in her place. Sia used the free time to write a number of new songs, some of which were given to Christina Aguilera -- who used them for her 2010 release, Bionic -- while others were compiled onto Sia's fourth solo album, We Are Born. ~ Andrew Leahey, Rovi
