“If someone tells me one more time: ‘Enjoy your youth,’ I’m gonna cry” — Olivia Rodrigo, “Brutal” (2021)

Teen angst has long been a catalyst for stirring music that captures the anxieties and selfdoubts of a generation, as the lyrics to “Brutal” so readily attest.

For Olivia Rodrigo, who turned 19 on Feb. 20 and won three Grammy Awards on April 3, teen angst also has been a catalyst for stardom beyond her wildest dreams.

A Filipino American born and raised in Southern California, Rodrigo’s swift rise to musical fame is a matter of record.

Her chart-topping debut album “Sour” was released last May. It came out only three months after her debut single, the all-lower-case “drivers license,” broke Spotify’s record for the most streams in one day for a non-holiday song. That’s a record Rodrigo broke the following day.

Ultimately, “drivers license” also broke the global record as the most requested song in one day on Alexa. It became Spotify’s most streamed song of 2021 while “Sour” became Spotify’s most streamed album of last year. She has more than 20 million Instagram followers.

It’s not surprising, then, that Rodrigo’s recently launched debut concert tour sold out from coast to coast in an instant. Ditto in Europe, where she’ll perform in multiple countries in June and July.

But what’s most notable about this former Disney-channel-star-turned-international-music-phenom isn’t her eye-popping sales figures. It’s her ability to vividly convey feelings of insecurity — about life and love, hopes and fears, the pressures of being a teenager grappling with everyday issues — at a time when much of the world seems on the brink of imploding.

Over the past 17 months, Rodrigo has captured the zeitgeist for her generation like no one since Billie Eilish, now 21, who was a five-time winner at the 2019 Grammy Awards.

Both are exemplars of “bedroom pop,” a tag that describes the exact location where they write and hone many of their respective songs.

But where Eilish favors a more layered musical mode that employs lots of digital technology, Rodrigo generally favors a piano and guitar-driven approach that is equal parts pop and emo, folk and rock, confessional ballads and inyour-face punk-pop.

Granted, Rodrigo is not a musical shapeshifter or a cutting-edge innovator. And her singing, while warm and affecting, is not technically astounding.

But those are pluses for Rodrigo. Her songs — nearly all of which are co-written with Daniel Nigro — are uniformly well-constructed and her lyrics are commendably candid. They resonate with Rodrigo’s largely young female audience precisely because her singing and her lyrics are, like her, so relatable.

Failed romances and breakups are an impetus for most of Rodrigo’s songs. Like many teens, she sets high expectations for herself, then laments her inability to live up to them.

But on one song on “Sour,” the album-closing “hope ur ok,” she looks outside of herself rather than in. Its lyrics first chronicle a boy who was a victim of child abuse, then a gay girl whose family rejected her, prompting Rodrigo to sing: “Does she know how proud I am she was created/ With the courage to unlearn all of their hatred.” It’s exactly the kind of heart-on-sleeve sentiment the 19-year-old Jewel might have written and sung when her musical career started to soar, back in the second half of the 1990s.

Whether Rodrigo’s career endures for another two decades, or peaks and ebbs in a few years, is unclear. It is also unclear if she has had time to develop much stagecraft on what is only the first tour concert tour of her young career. But in the here and now, her timing seems almost perfect for capturing the moment — and with it, similar moments for millions of her listeners.
