After co-creating the music video for her blockbuster 2014 hit “Chandelier,” Sia got the directing bug. The Adelaide native co-wrote a screenplay with children’s book author Dallas Clayton, and eventually signed on as director.

The album features guest appearances from Labrinth, Burna Boy, and David Guetta, but let’s be honest: There’s no competing with a voice like that.
