The return of Maddie Ziegler as a wigged and young Sia is totally welcome since the video for Chandelier earlier this year. The concept of the video for Elastic Heart is brilliant, ingenious – fitting the track, the film and Sia’s aesthetic. Yes Shia LaBeouf is overacting, but this is intensely part of the charm. Elastic Heart is directed by Sia and Daniel Askill and choreographed by Ryan Heffington.
