Lorde may not be a princess cut from marble, but her American Music Awards performance of “Yellow Flicker Beat” was really solid. She started inside a red cube, which was lifted above her. She revealed herself to the audience and performed her signature dance moves — frenetic and passionate — around stoic people dressed in white. As the lights went down, she dragged her fist across her mouth, smearing her dark lipstick on her cheek.

Sunday night marked the first time Lorde performed the track live. “Yellow Flicker Beat” is the lead single from the soundtrack for “The Hunger Games: Mockingjay – Part 1″ that Lorde herself curated. “Thank you for so much love on one of the scariest, most exciting things I’ve done,” Lorde tweeted on Monday, the day the soundtrack was released. “Listen to it; buy it. ENJOY.” Way ahead of you on that one, Ella.

(Oh, and Taylor Swift sang along the whole time.)
