Belia Winnewisser and Fatuma Osman have known each other since childhood, a friendship rooted in shared afternoons of music and late 90s/early 00s girl core. Their first joint debut EP Vertex, released through the Swiss label Light of Other Days, emerges as both a continuation of that bond and an exploration of process, weaving together collective memories with their present-day musical language.

Resisting polished closure, the record circles around the idea of limerence in sound: suggesting rather than declaring, outlining atmospheres that leave room for the listener’s imagination to fill out the blanks. Across its five tracks Belia and Fatuma oscillate between the personal and the universal, immediacy and nostalgia. The opening track Emerald rises like morning light; fragile, blissful, and quietly radiant. Covering Madonna’s 80s single Angel feels natural and slots seamlessly into the EP’s arc: as a defining pop presence of the last four decades, she embodies less an idol than a subtle compass. Surrender, the first track on the B-side, draws you into the club, vibrating between vulnerability and release. Each step extends their vision further, revealing a cohesive body of work.

Vertex holds opposite poles in tension, creating a space where vulnerability and intensity create dialog. What lingers is a realm of possibilities: a conversation between two friends and collaborators who understand that sound can be as much about what is left out as about what is expressed. Vertex documents their progression, marking a milestone without concluding it.
