Saint Demarcus is a London-based alt-R&B artist blending lo-fi textures, indie soul, and introspective songwriting, with soft vocals and atmospheric, minimal production rooted in modern bedroom R&B. "Lifeline" is about that one thing everyone has that keeps them going when everything else is falling apart. It might be a person, a memory, or even music itself. A quiet anchor in chaos, capturing resilience, vulnerability, and emotional survival.
