Apple ended their iPhone 7 announcement in San Francisco with a performance from Sia, who delivered the live debut of her new single “The Greatest.”
Sia, hidden behind a black-and-white wig and massive magenta bow at the side of the stage, sang the track as a quintet of dancers spun around center stage, juxtaposing its action with Sia's "The Greatest" video that was projected on a screen in the background. Unfortunately, Kendrick Lamar did not reprise his guest turn with the singer onstage.
Following "The Greatest" performance and a quick costume change into a black wig and giant white bow, Sia and her frequent visual muse Maddie Ziegler brought their breakout single "Chandelier" to the Apple stage.

Earlier in the event, Apple confirmed many of the rumors surrounding their much-anticipated device, including the elimination of the traditional analog headphone jack, improved battery life and camera, water resistance and stereo speakers. The event kicked off with a video of Apple CEO Tim Cook hitching a "Carpool Karaoke" ride with James Corden and Pharrell Williams.
