​It’s been a long time since a phenomenon as talented, authentic, complex and delightfully of the moment as Billie Eilish took over the Grammys​. She turned five of her six nominations into wins, victorious in all four major categories (album, song and record of the year, plus best new artist), becoming the first artist to sweep since Christopher Cross in 1981. At 18, she’s the youngest person to win album of the year. It is all richly deserved: “When We All Fall Asleep, Where Do We Go?” redefines teen-pop stardom, as Jon Pareles wrote in his review of the album. Eilish (working with her producer brother, Finneas O’Connell) digs her shapely talons into the conflicts that throb in our minds like her meticulously constructed tracks: anxiety and confidence, love and terror, fairy tales and reality. She is a genuine melting pot of pop history — goths, rappers, confessional singer-songwriters, all tucked into baggy clothes that defy all kinds of stereotypes. “Why,” she cried into the microphone as she accepted her first televised award, for song of the year. “Aye yi yi,” she started her second, for best new artist. “Please don’t be me,” she mouthed as album of the year was being announced. Finneas spoke up during their speech for the LP: “We wrote an album about depression and suicidal thoughts and climate change and being the ‘Bad Guy,’ whatever that means,” he said, “and we stand up here confused and grateful.” It was simply proof that sometimes the music industry does get it right.
