Mustii, whose real name is Thomas Mustin, was born in Brussels on November 21, 1990. He is a multidimensional Belgian artist: singer, songwriter, actor, and director. A theater graduate from the Institut des Arts de Diffusion in 2012, he has excelled on stage (notably in Romeo and Juliet, Hamlet) and on screen in series such as La Trêve or films like The Royal Exchange, which earned him the Magritte Award for Best Male Newcomer in 2019. Alongside his acting career, Mustii has built a strong musical path: after a remarkable first single, The Golden Age (2014), he released two albums – 21st Century Boy (2018) and It’s Happening Now (2022) – blending electro-pop with dramatic melodies. In 2024, he represented Belgium at the Eurovision Song Contest with Before the Party’s Over, and also served as a judge on Drag Race Belgique. His voice, both powerful and fragile, his stage presence, and his artistic commitment make him a unique figure of Belgium’s contemporary scene.
