The electric energy of America’s Got Talent Season 21 reached a fever pitch during episode two when teenage duo Nyjah Music and Zyah Rhythm completely stole the show. Hailing from Oahu, Hawaii, the brothers, ages 16 and 15, proved they were destined for stardom from birth, as Music and Rhythm are their actual legal middle names. Instantly separating themselves from typical standard cover act auditions, the incredibly talented siblings stepped up to the microphone and confidently chose to perform a stunning original song titled “Heartbeat.”

The impact of “Heartbeat” on the judges was immediate and overwhelming. Howie Mandel compared their infectious vibe to former winner Grace VanderWaal, creating a massive full-circle moment since watching VanderWaal win initially inspired the boys to audition. Sofia Vergara described their performance as being like heaven on that stage. While Mel B admitted she didn’t love the song itself, she was completely blown away by their stunning vocal blending. Ultimately, Simon Cowell secured their confidence by validating their undeniable talent, securing four enthusiastic yes votes. Watch their incredible audition below.

The public reaction to their technical performance and stellar songwriting was incredibly positive. Fans were quick to emphasize just how polished and radio-ready their young voices are. One viewer gushed, “Their harmonies were gorgeous and amazing.” The original track clearly landed deeply with audiences everywhere, proving their maturity as artists extends far beyond their teenage years. Another fan praised the duo’s exceptional songwriting abilities, passionately noting, “This could easily be someone’s wedding song. so beautiful.”

Remarkably, the brothers are the nephews of pop icon Bruno Mars and drummer Eric Hernandez, while their mother and aunts formed the girl group The LYLAS. Yet, they never leaned on their family’s fame. A commenter observed, “I love that the ONLY reason I know they are related to Bruno Mars is because of reading the comments here. The boys never flaunted about that once to try and show off their connections or whatever. Making their own mark with their own skills and talent.” Before capturing hearts on the AGT stage, the talented brothers recorded a special track for a major Disney soundtrack.

Building on their viral TikTok and Instagram success covering traditional Hawaiian mele, their magical voices landed them a cover of Elvis Presley’s “Burning Love” for the 2025 live-action Lilo and Stitch remake, produced by their famous uncle. Back on the AGT stage, the overwhelming community support was palpable, and The Music Man is here for it. Behind the scenes, viewers were deeply moved by the heartwarming sight of their mother supporting them offstage. As one fan put it, “So happy just for the mom! She’s beaming with pride!”

The Hawaiian brothers’ journey on America’s Got Talent has only just begun, but they have already left a permanent mark on the hearts of viewers worldwide. Earning their spot purely on talent, the duo proved they have what it takes to deal with the music industry. The performance was so spectacular that another viewer went as far as to say, “That should have been a Golden Buzzer!” With breathtaking harmonies, humble attitudes, and an infectious stage presence, Nyjah and Zyah are undoubtedly the next big phenomenon in pop music.
