Sia took the stage to sing her biggest hits at the iHeart Radio Music Festival.
If time wasn't a factor at iHeart, the This Is Acting singer could've rocked the house all night long. But in the 20-some minutes she was allotted, Sia powered through songs with help from her frequent collaborator and dancer, Maddie Ziegler, who bounced around the stage to Sia's No. 1 charting "Cheap Thrills," "Elastic Heart," "Titanium" and "Chandelier."
At one point, Ziegler helmed the stage wearing a giant panda mask and fought with a male dancer wearing a stoned-looking jackal guise. Bizarre, imaginative, mysterious. Very Sia.
