Even with her face still hidden from view at the Grammys, Sia still finds new ways to give compelling performances of her singles. With Maddie Ziegler and Kristen Wiig on dancing duties, Sia faced the back wall of a pop-up set featuring a messy room. As she belted out "Chandelier," Ziegler and Wiig wore matching blonde bob wigs and stripped down by the end of the performance to nude bodysuits. Their choreography was a mix of both "Chandelier" and "Elastic Heart," with the two dueling sides of Sia battling it out before uniting during the performance.
Shia LaBeouf, the star of Sia's controversial "Elastic Heart "video, introduced the performance with a dedication to the singer. Sia earned four nominations, including a nod for Record of the Year and Song of the Year. Her last nomination was in 2013 for "Wild Ones," her collaboration with Flo Rida.
Having shifted her career primarily to songwriting and guest appearances, 1000 Forms of Fear had been the singer's big return to being a solo artist. Given her past struggles with fame, Sia's performances have been unconventional, with the vocalist rarely showing her face and shying away from being the star of her public appearances.
Sia has been bringing Ziegler with for most of her TV appearances, with the young dancer doing reinterpretations of her quickly viral video routines. Most recently, the pair appeared on The Ellen Degeneres Show, where Sia announced her Grammy performance, to perform "Elastic Heart." In the past, she has also performed with Lena Dunham, with Shia LaBeouf co-starring with Ziegler in the "Elastic Heart" video.
