What started as a mysterious TikTok hit quickly grew into the number 1 in the Netherlands: Lotje. The Utrecht trio behind the track, Roeland Beelen, Maurits Beelen, and Jopke van Dobbenburgh, surpassed established names like the Bankzitters and Roxy Dekker with their infectious and unique sound. With millions of streams and thousands of videos, Lotje is the surprise of the moment. During Zomerparkfeest, Roeland and Jopke will bring the viral energy live to the stage. Who or what Lotje exactly is? That remains a secret for now, but standing still will be difficult.
