Backed only by her brother / colleague Finneas O’Connell and a slew of instruments and a drummer, Eilish was a confident, rambunctious performer, even when it was evident when she was occasionally slowed down that she was overwhelmed by the massive opportunity. "I don't deserve this," she said at one point, clearly in the sheer number of people in front of here. – with the exception of a troupe of dancers in jaw-dropping choreography on one song, and Eilish herself performing on a bed as it dangled about the stage on the highlight “Bury a Friend,” her persona menacing a la the girl in “The Ring, "as the bed is angled itself towards the audience. A collaboration with rapper Vince Staples on "Watch / & Burn" was a bust: his mic was accidentally muted for the entirety of the song. By the end of the set, for "COPYCAT," Eilish had the crowd in her small palms, making everyone duck-and-jump in time with the song's peak. It's an old gimmick – but most of Eilish's performance, one that is fully delivered on.
