A pop star who could never be pinned down, singing the one genre that never needed her to be.

y late 2012, Kelly Clarkson had spent a decade being asked, one way or another, what kind of artist she actually was. Pop belter, country crossover, arena rock voice — the labels kept shifting, and Clarkson, tired of choosing, decided the way through was sideways: make a Christmas record, a genre with no allegiance to any single sound, and let herself be all of it at once.

She started writing in December 2012, a full year ahead of release, on purpose — she didn’t want to be the person hunched over a piano in July trying to conjure sleigh bells in ninety-degree heat. Among the songs she wrote that winter with producer Greg Kurstin, one in particular felt different the moment it came together: “Underneath the Tree,” built on the kind of bright, bell-heavy arrangement that immediately invited comparisons to a song already sitting at the top of every December playlist in America.

Clarkson and her team weren’t shy about the comparison. They’d watched what “All I Want for Christmas Is You” had done for Mariah Carey two decades earlier — a song that made an artist synonymous with the season rather than just visiting it for one album — and set out, quite openly, to write something with that same kind of staying power. Kurstin leaned hard into a Phil Spector-style Wall of Sound treatment, sleigh bells stacked over horns stacked over Clarkson’s voice pushed right up to the edge of its power, and the result landed exactly where they’d aimed: critics started calling it a future standard before the album had even finished its first week on the charts.

The album itself, Wrapped in Red, became the best-selling Christmas release of that year, and its title track — inspired, fittingly, by a scene from Love Actually — carried the same Spector-indebted lushness as its lead single. Clarkson filled out the rest of the record with covers chosen less for obligation than affection: “Have Yourself a Merry Little Christmas” for its plain sweetness, “Run Run Rudolph” because she simply likes rock and roll better than most things.

There’s something worth noticing in how deliberately “Underneath the Tree” was built to sound old. Nothing about a Wall of Sound arrangement is contemporary; it’s a 1960s production technique, revived on purpose, aimed at a very specific kind of nostalgia even for listeners too young to have any memory of the original sound. Clarkson wasn’t trying to reinvent Christmas music. She was trying to write herself permanently into it, on a shelf already crowded with better-known names, using the same trick that’s always worked: make it sound like it was already there.
