In 2017, her song 'Such Words' reached more than 50,000 plays on Spotify 24 hours after its release. Ghostly Kisses was also part of the International Festival of Jazz of Montreal and Festival d’Été of Quebec and opened for international renowned artists such as RY X, Charlotte Cardin, Trixie Whitley and Milk & Bone in Canada and the US.
In 2018, she released 'The City Holds My Heart - EP', a 5 pieces album produced by Louis-Étienne Santais (Fjord) and inspired by the sonic textures of the 90's. Unfolding around Margaux’s soft voice, these songs progressively reveal different drums, synths, string arrangements and piano layers. Early 2019, Ghostly Kisses did her first official tour in Canada and played a few shows in the United States. She sold out half of her shows in Canada (Toronto, Montreal, Quebec City, Lévis and Beloeil). She was also officially chosen to showcase at SXSW in Austin in March 2019.
