The career of Thomas Mustin, Mustii's real name, is a smooth one. After studying acting, he was quickly cast in theatre (Romeo & Juliette, Hamlet, etc.), television (La Trève, Je Voulais Juste Rentrer Chez Moi alongside Mathilde Seigner) and cinema (Grave, Un Petit Boulot, L'Échange des Princesses, etc.), and was awarded the Magritte for Best Young Male Talent in 2019.

Meanwhile, his musical talent is also noticed, as a singer songwriter under the pseudonym Mustii. His first EP is released in 2016 and thanks to the single The Golden Age, performances at many festivals follow, including the Brussels Summer Festival, the Francofolies of Spa, Les Ardentes, Les Solidarités, Les Nuits Botanique, .... His success is crowned with the award for Revelation of the Year at the D6bels Music Awards. Shortly after, his first album 21st Century Boy is released in autumn 2018.

Even though, after 2 sold-out ABs, he is concentrating on writing a new album (which will be released on 21.01.22), the actor in Thomas is not resting on his laurels either: he is playing in the film Vous n'aurez pas ma haine, alongside Pierre Deladonchamps and Camélia Jordana, in the French series L'île aux 30 cercueils and will be back in the theatre as Hamlet in 2022.

Following the release of his latest single Give Me A Hand, the Belgian artist has announced the first dates for his new It's Happening Now tour, which also stops in Brussels!
