Billie Eilish's long-awaited Tiny Desk concert has arrived as NPR Music shared the singer's stripped-down cubicle performance on Thursday. "Wow. This is nerve-wracking," Eilish told lucky NPR employees between songs.

Eilish and her brother Finneas, as well as Andrew Marshall on drums, Solo Smith on bass, and Abe Nouri on piano, performed four stripped-to-the-essence songs for NPR: “The Greatest,” “L’Amour de Ma Vie,” “I Love You,” and “Birds Of A Feather.”
