Influenced by his father's musical tastes and his own personal discoveries, Léman's music mixes rock (AC/DC, Radiohead) and electro (SebastiAn, Justice), with touches of metal (Slipknot) and rap (Orelsan, Stromae). Originally from the Franco-Swiss border, he has been playing guitar since his teens, finishing his baccalaureate before attending the CFPM in Lyon and the Villeurbanne Conservatoire.
After starting out in bands, Léman launched his solo career and was noticed during the 6th edition of The Voice. His EP "On est Plein" reflects his personal emotions and observations, with pop-rock songs reminiscent of Muse and Daniel Balavoine.
In "JVQTSM", he deals with anger with an upbeat melody, and contrasts emotions in "On attend", evoking his father and alcoholism. "Petit Garçon" tackles burning societal themes from a child's perspective, criticizing sexism, racism and homophobia.
He also denounces social dysfunction in "Les Plus Bornés", underlining democratic neglect with persistent hope. His video clip, inspired by Eugène Delacroix's "La liberté guidant le peuple" (Liberty guiding the people), left a lasting impression, with its lyrics resonating even at demonstrations.
