Katell Chevalier was born in Calais and even though her family moved between France, Belgium and the Netherlands often, Katell was raised with the French language consistently. In 2006, she left Paris in order to pursue her vocal studies at the ArtEZ Conservatory in Enschede. During her studies, Katell started to write and compose her own songs.
In 2012 Katell released her debut EP “Emmène-Moi”, containing fairy tale themed acoustic songs such as “Robin de Bois” and “L’Amoureuse Stand-By”. In comparison her first full-length LP “Cœur D’artichaut”, which was released in 2014, is a little less folk influenced and more pop oriented. It featured Katell’s song of praise about the French cycling contest Tour de France, “Vite Vite!”. In 2018 another EP followed, titled “J'avance”, on which Katell incorporated more electronics into her music. In the summer of 2020, Katell released her new single Amsterdam - Paris, a song giving tribute to the two cities Katell calls home and which features her singing in both French and Dutch for the first time.
