t’s old ground to chew over, but there are problems in providing an artist whose put one hugely successful record and then they are furnished with a prominent slot at a major festival. After all, a prominent slot means more time. More time means more songs. But you might not have that many to choose from. How do you fill it without it sagging in the middle? 

Sadly, Eilish doesn’t quite manage to overcome this obstacle no matter how much chutzpah and vigour she puts into her performance. It’s certainly an energetic show. She leaps and bounds about in a trouser suit bedecked with the Blue Meanies from the Beatles’ Yellow Submarine which has Stella McCartney’s name tapered down the side of it. Billie Eilish is self-aware and kooky. Her effervescent energy, bounding about the stage without nary a let up.

She kicks things off with the propulsive, throbbing bass of Bad Guy, which sounds like a twisted Bat For Lashes. My Strange Addiction follows and the crowd are at her mercy. She asks them to crouch down at one point, and everyone observes the request. The lulls come, but the likes of Wish You Were Gay and the closing Bury a Friend more than make up for it. 

Shades of Lykke Li cut through from time to time, but Eilish is a poster girl for people of all ages. This is one self-assured artist who has quickly risen in the pecking order in pop’s pantheon. It will be interesting to see where she goes next, certainly, but she made quite an impression at Worthy Farm. She said that she should see her in a crown, well they’d better get it ready. If she can follow up on her promising debut then we will really be able to acknowledge this new force in town.
