Watch Sia Go All Performance-Art On VH1’s SoundClash

The entire point of SoundClash the new ?uestlove-produced and Diplo-hosted VH1 show, is to throw a set of disparate artists up onstage and watch what happens. Last week’s episode, for instance, had T.I. sharing a stage with Fall Out Boy and London Grammar. Last night’s episode, meanwhile, had Sia, Ed Sheeran, and Grouplove. The group performances aren’t online yet, but Sia’s solo ones are. She turned all of her songs into grand performance-art spectacles, as she’s done more than once lately. Lip-syncing surrogates! Hidden faces! An entire audience in Sia wigs! Below, watch her performances of “Chandelier,” “Elastic Heart,” and “Big Girls Cry.”

Sia’s album 1000 Forms Of Fear is out now on RCA/Monkey Puzzle.
