She taught herself piano at a young age and began writing songs by fifteen as a way to understand the world and express her emotions. This search for balance, between light and dark remains at the heart of her music. Her dreamy sound floats somewhere between pop noir and electronica, drawing inspiration from artists like Radiohead, Lana Del Rey, Taylor Swift, Bon Iver, and Massive Attack. With her debut album Symbiosis (2023), Leah reached a wider audience. She performed at festivals such as Wildeburg, Motel Mozaique, Rapunzel (hosted by Bas Kennis of Bløf), and Grasnapolsky, and earned airplay and live sessions on Dutch radio stations including 3FM and NPO Radio 2. Her music also caught the attention of Rob Stenders on Radio Veronica. Leah sold out club shows at venues like Paradiso, Patronaat, and Tivoli, and supported acts such as Blaudzun and The Veils on their European tours.
