In 2010, she won the prestigious singing contest ‘Concours de la Chanson de l’Alliance Française’ in Amstelveen.
In 2012, she released her first EP called 'Emmène-moi’ and toured with the band in various theatres in the Netherlands.
Her album “Cœur d’Artichaut” has been released in November 2014 . The single “Vite Vite!’, Katell’s song of praise about the cycling race of her homeland could be heard on dutch national radios.
In 2016, she presented herself at the blind auditions of the Voice of Holland with the French song “Formidable” by Stromae ” – making the four chairs of the jury turn.
With the help of her coach Guus Meeuwis, Katell reached the live shows and continued to sing in French: “Amsterdam” from Jacques Brel, a translated version of Adele’s “Hello” and also a very touching reappropriation of Meeuwis’ “Brabant”, which she transformed into “Paris”. All sang in her native language.
In collaboration with the Dutch production company The Dreamlab, Katell toured in theaters in the Netherlands with “Deux Voix”; a show including songs of Jacques Brel and Stromae, mixing the music styles of these two great artists.
In May 2018 Katell released her EP “J’avance”; electronic elements and acoustic instruments merging into French songs.
