Lorde remembers her first Portland show well.

It was a little over four years ago, at Crystal Ballroom. Returning to headline Moda Center on March 10, the 21-year-old pop prodigy recalled the details—how she was forced to perform in the mid-afternoon, how Vampire Weekend played after her, and especially, how much smaller the crowd was then.

But while last year's Melodrama may have bumped her up a touring weight class as far as touring goes, she assured fans her fundamental nature as as performer hasn't changed.

"My thing is to speak to people in a giant room like I'm just sitting down and having dinner with them," she said.

Indeed, in comparison to the dizzying spectacles that have hit town recently, the New Zealand-born singer's first stab at an arena show resembled a one-woman theater production. Her only major set piece was a glass box resembling a see-through shipping container, which alternately levitated and sunk into the floor, and her artful dancers registered as wisps.

The spareness befit her music: Hits like "Tennis Courts" and "Royals" make better use of empty space than anything on radio, buzzing and snapping into the void. Similarly, as a vocalist, Lorde's strength is her directness—the most stunning moment of the night might have been her piano-accompanied cover of Frank Ocean's "Solo," and it came off less like a vocal workout than a dramatic journal reading.

That doesn't mean she's incapable of huge moments: The sing-along to "Perfect Places" was massive, and "Green Light," which closed the set, is exhilarating in a way few pop singles ever are. The only difference is that, unlike many of her contemporaries, she's bold enough to let those moments speak for themselves.
