Sia has premiered her new single 'Together' from her upcoming motion picture and album Music.

The colourful music video stars Maddie Ziegler, who also stars in the full motion picture as a young girl on the autism spectrum.

Sia's directorial debut also features Beto Calvillo, Mary Kay Place, Hector Elizondo, Leslie Odom Jr and Kate Hudson, who plays the newly sober Zu.

The story begins when Hudson's character becomes the sole guardian to her half-sister Music (Ziegler).

The screenplay for Music was penned by Sia & Dallas Clayton, and is based on a short story Sia wrote back in 2007.

Lead single 'Together' was written by Sia & Jack Antonoff, and produced by Antonoff alongside Jesse Shatkin.
