Nyjah Music and Zyah Rhythm turned their June 9 appearance on America’s Got Talent into a clean advance, singing their original song “Heartbeat” and leaving the judges with four yeses. For Nyjah Music, 15, the performance put a national spotlight on a teenager who was already being watched online.
That matters now because the audition landed just as viewers were still learning who the brothers are and why their name had started moving across Instagram and TikTok. Nyjah Music and Zyah Rhythm, 15 and 16, are from O‘ahu, Hawaii, and had already built a following online, with 280K followers on Instagram and 1.78K subscribers on YouTube, before stepping onto the America’s Got Talent stage.
Their rise did not begin with this show. The brothers were said to have drawn attention through viral Instagram and TikTok performances of old-school R&B covers, Hawaiian mele and ballads, then widened that reach with a GAP commercial in November 2024 and a cover of Elvis Presley’s “Burning Love,” which was featured on the soundtrack for the 2025 live action remake of Lilo and Stitch. Those earlier appearances gave their original material a ready-made audience when “Heartbeat” aired.
What was not said on stage was just as notable as what was. The brothers did not mention their connection to Bruno Mars during the audition, even as their music has been produced by him. They also shared a photo with Bruno Mars while working on their Lilo and Stitch track, a detail that helps explain why the performance drew attention beyond the usual talent-show crowd. Their family background runs through the same story line, since Nyjah Music and Zyah Rhythm are the sons of Tahiti Hernandez Kemper and Billy Kemper.
The yeses move them into the next phase, and the show’s own attention can only grow from here. Talent Recap said the pair may return for Judge Callbacks this season and told viewers to tune into America’s Got Talent on Tuesday, June 16, but that return was not confirmed. For now, the unanswered question is not whether the brothers can sing. It is how much of their run will be shaped by the Bruno Mars connection they have so far let the music carry for them.
