Adelaide-born singer-songwriter Sia is back with a bizarre new music video, for her latest song ‘Elastic Heart‘.

The minimalistic, grey-palette video, choreographed by Ryan Heffington, features none other than controversial Hollywood actor Shia LaBeouf and Maddie Ziegler from Dance Moms, wearing nothing but beige underwear.

The unlikely duo (28 and 12 years old respectively) dance, wrestle and battle in a large cage like primitive animals to Sia’s piercing electro beat. Her emotive vocals soar over house backing and pokey chorus chants.

Ziegler, who also starred in Sia’s viral ‘Chandelier’ video, once again dons the Sia blonde-bob wig, taunting an oiled-up and beefed-up LaBeouf with agile assaults. The pair appear to be channelling a strained father-daughter relationship, with many speculating the song refers to Sia, her mental illness and her own father.

The new video is odd to say the least, but the result is somehow emotional and entrancing. LaBeouf’s performance in particular is surprisingly moving.

‘Elastic Heart’ is off Sia’s 2014 released album 1000 Forms of Fear.
