Billie Eilish is just 21 years old but it’s been several years already that this global pop sensation reigns supreme. She’s beaten all the records, (multiple award-winner, youngest artist to ever perform a James Bond track) and her music is a triumph (her second album dominated the charts in 28 countries). This committed musician has had breath-taking global success before she was even an adult. It’s the result of an intensely close relationship with her big brother Finneas (who accompanies her on tour), her music has revolutionised pop by inventing much imitated but never equalled new practices: a way of singing that’s full of sighs and nuances, close to the microphone, with minimal but delicately formulated arrangements and lyrics of a rare maturity, at once clever and original. Everything required to make you Happier Than Ever when you see her on stage.
