Two teenage brothers from the North Shore of Oahu walked onto the America's Got Talent stage last week with an original song, a quiet confidence, and a secret they were not telling anyone.
Nyjah Music, 16, and Zyah Rhythm, 15 - sons of Tahiti Hernandez-Kemper, one of Bruno Mars' sisters - performed their original song "Heartbeat" on the 2026 edition of AGT and earned four unanimous yeses from the judges. They did not mention their famous uncle once.
Howie Mandel was among the first to react. "I have to say your voice reminded me a little bit of Grace VanderWaal," he told the duo. "I think you're going to be memorable. I think people are going to remember your name, and I just think they are stars." Sofia Vergara called them amazing.
The VanderWaal comparison landed with extra meaning - Zyah revealed that watching Grace VanderWaal's AGT audition as a child was part of what inspired them to audition in the first place.
What the judges did not know - and what the boys never volunteered - was that their music is produced by one of the biggest names in the industry. All of Nyjah and Zyah's music is produced by their uncle, Grammy-winning artist Bruno Mars. They are perhaps best known for their cover of Elvis Presley's "Burning Love," featured on the soundtrack for Disney's 2025 live-action remake of Lilo & Stitch.
But before any of that, there was a grandmother and a karaoke machine.
"When we were young, our grandma used to sing to us, and we used to do karaoke with her when we were little," Zyah shared in a previous interview. "Singing is in our bloodline." Raised with deep Hawaiian roots, the brothers built their following through viral covers of old-school R&B, Hawaiian mele, and ballads on Instagram and TikTok - long before the spotlight of a national stage found them.
That kind of origin - music passed down through family, rooted in something quieter and more sacred than fame - is what makes their AGT moment feel like more than a talent show audition. It feels like a testimony.
Nyjah and Zyah are through to the next round. The rest of America is just now catching up.
