A Parisian native, Avalanche, a child of the 90s, began writing songs at the age of 6, recording them in his bedroom on his mother's old ghetto-blaster. Influenced by French chanson and artists like Claude Nougaro, he later embraced Soul, Pop, and Electro music during his adolescence, refining his songwriting over the years.

Between 2014 and 2019, Avalanche contributed to the songwriting of artists such as Juliette Katz, Enchantée Julia, and Maureen Angot. However, his desire to express himself through his own voice grew stronger, evolving from a childhood dream into a visceral necessity. After years of honing his craft, Avalanche launched his solo project towards the end of 2019, crafting a delicate and modern Pop sound that balances heart and body, dance and emotion. His debut single, "Partir à temps," was released on May 13, 2021, following his first concert in Paris at DiSQUAiRES at the beginning of 2020, solidifying his passion for the stage.
