Layla Clark is back in the online spotlight after a video of her playing marimba in Thomas Jefferson High School and marching band's rendition of AC/DC's "Thunderstruck" spread on X on November 5, 2026. The clip pushed a performance that had already gone viral a year ago into a new wave of attention.
The renewed interest matters because Clark's name is now drawing viewers far beyond her school, even though the performance itself is not new. A year ago, her mom recorded the marimba part and the video picked up millions of views on TikTok, turning a school band moment into a much bigger internet story.
Clark said learning the piece was no small task. "Yes, it was so hard," she said, adding that it took her forever to get it down. Even now, she said, "I still don't have it perfected." That is part of why the video keeps landing with people: it shows a polished-sounding performance built on a lot of work that the player herself says is still not finished.
The scale of the response is what has kept it moving. Clark said her school e-mail was blowing up with teachers telling her, "Did you see your video? You're viral. You're viral." She also said people tell her the clip makes them happy. The attention has reached far enough that a student performance at Thomas Jefferson High School is now being watched as an internet event, not just a school-band moment.
There is still one detail the latest wave does not answer: who posted the video on X. That gap has not slowed the circulation, but it does leave the second burst of attention attached to a clip whose path online is not fully clear. Clark, meanwhile, is already looking ahead. She is a senior and said she is going to college next year with hopes of becoming a veterinarian.
For now, the story is less about a perfect performance than a teenager whose marimba version of "Thunderstruck" keeps finding a larger audience each time it returns online.
