LMNT 115 is an Australian writer-producer duo built around songwriter “Z” and producer Fabien Bethuizeau, introduced as a collaboration-first project that pairs pop toplines with dance and cinematic electronic production. The act launched in late 2024 with the debut single “Close to You” featuring Sadie Rose Van, setting the template for guest-driven releases rather than standalone records. In 2025, LMNT 115 expanded that approach with “Holding On To Us” featuring Brando, then followed with “Out Of The Dark” featuring Zak Abel, a track that further positioned the duo in the pop-dance lane. Later in 2025, LMNT 115 released “Paradise” with Daya, continuing the same model of pairing their production identity with recognizable vocal collaborators, before closing the year with “Fuse,” a collaboration with Ky-Mani Marley. These releases were collected on the debut EP Isotope (2025), which functions as a concise statement of the duo’s first era—five tracks that connect the project’s November 2024 launch to the late-2025 run of singles, with each song framed as a feature-driven chapter rather than a separate detour.
