Last month, Stephen Colbert interviewed Lorde, whose new album Solar Power comes out in August. At the time, Colbert was already hosting guests and audiences in his studio, but Lorde wasn’t there; Colbert interviewed her remotely. During their conversation, though, Lorde promised that she would come see Colbert at his studio. Last night, she made good on her promise. In the rooftop of Colbert’s Manhattan studio, Lorde performed her big single “Solar Power” live for the first time.
