Directing new movie Music most 'exciting', 'meaningful' thing Sia says she's 'ever done'

Sia is a musician best known for her chart-topping dance anthems and the wig obscuring her face from her growing fame.

Fame never sat well with her, but it was impossible to avoid. Her gargantuan hits 'Chandelier', 'The Greatest', and 'Cheap Thrills' all started with the barnstormer which kicked off her career - the song she wrote for David Guetta, the first of what would be nine massive club collaborations.

Now, she's come off the dance floor, taken off her wig, and directed her first film, Music.
