Echosmith's Cool Kids Moment: Where Are the Sierota Siblings Now?

A little over a decade ago, four siblings from Los Angeles dropped a song that became the unofficial anthem for every underdog who ever wanted to fit in. Echosmith—Sydney Sierota, Noah Sierota, Graham Sierota, and Jamie Sierota—hit the cultural moment with Cool Kids in 2014, and the track lodged itself permanently in the pop-culture zeitgeist.

The song’s ascent was swift and unapologetic. Cool Kids climbed to number 13 on the Billboard Hot 100, a feat that doesn’t sound like chart dominance until you remember this was a band fronted by siblings who basically channeled every millennial’s desire to belong while insisting they didn’t care if they did. That contradiction—the vulnerability wrapped in defiance—is what made the track resonate. It still does. Spin it today and you’re instantly transported back to 2014, which tells you something about how deeply it embedded itself in our collective memory.

More than a decade later, the question isn’t whether Cool Kids remains iconic. It absolutely does. The real intrigue is what these cool kids have been up to since then. The Sierota siblings didn’t vanish after that breakthrough moment—they’ve continued creating, touring, and evolving as artists. But the mainstream spotlight tends to move on, and it’s easy to lose track of what happens to one-hit-wonder bands or acts whose initial momentum doesn’t translate into sustained arena dominance.

That’s what makes the current moment worth paying attention to. Echosmith exists in that fascinating space where they’re remembered fondly but not constantly discussed. They’re the band people remember when a song pops up on a playlist, the group that shaped a specific era of pop music even if they didn’t dominate every chart thereafter. Seeing where they are now—how they’ve aged, what they’re working on, how they’ve grown—offers a genuine window into the long game of making music as a family unit, which is its own kind of rare and complicated achievement.

The Cool Kids era might be locked in 2014, but the band’s story didn’t end there. Sometimes the most interesting chapter of a band’s history isn’t their breakthrough—it’s what they build afterward, when the spotlight fades and they have to decide whether they’re in it for the long haul or just riding a wave.
