Fifteen-year-old viral singing phenomenon Emma Kok is back just in time for Christmas with another unforgettable collaboration alongside André Rieu. The young star once again proved she can light up an entire arena, as audiences joyfully danced and sang along to her spirited performance of All I Want For Christmas Is You.
Though Emma is still a schoolgirl, her voice carries the depth and confidence of a seasoned performer. Her soaring high notes — especially around the 0:45 mark and at the finale — highlighted her remarkable vocal control and maturity well beyond her years. But it’s not just technique that sets her apart; there’s a natural warmth and soulfulness in her voice that instantly draws people in. From the very first note, the crowd was moving, supported by the rich, polished sound of Rieu’s orchestra, which once again delivered flawlessly.
The performance quickly took off online, racking up nearly three million views after being shared on Rieu’s YouTube channel. Viewers flooded the comments with praise, calling Emma “otherworldly” and marveling at the joy of seeing a crowd fully present — dancing, smiling, and soaking in the moment instead of watching through phone screens.
This wasn’t Emma’s only standout moment from André Rieu’s Christmas concerts in his hometown of Maastricht. She also delivered a touching rendition of White Christmas, revealing a softer, more emotional side of her voice. Opening the song a cappella, Emma held the massive audience in silence — a breathtaking feat for any singer, let alone one just 15 years old — leaving many listeners visibly moved.
Born on March 12, 2008, in Maastricht, Emma first captured national attention after winning The Voice Kids in 2021. She continued her rise in 2023 by winning the debut season of Ministars with her performance of Voilà. André Rieu was so impressed that he invited her to perform with his orchestra — a decision that paid off in spectacular fashion. Their August 2023 performance in Maastricht went on to surpass 100 million views, becoming one of the most-watched videos on Rieu’s channel.
Once again, Emma Kok has shown that age is no barrier to artistry — and that her voice is fast becoming one of the most special in modern classical-pop crossover music.
