Sub Blue is a Liverpool-based artist who experiments with R&B, taking his name from his self-described style of music, "suburban blues", and bringing his own unique brand of introspective R&B. Featuring minimalist electronic production from US producers A.V. (Frank Ocean), and Grammy winner Sir Dylan (The Weeknd, Miguel, Logic), "Teen No More" is a thought-provoking listen exploring the complexity of growing up as a teenager. Speaking about the track, Sub Blue said: "I wrote 'Teen No More' about the fear of growing up and having to accept full responsibility for everything we do. As teens, we often live our life not really thinking or knowing what can happen next, but we have the confidence to know we are going to make things happen. That's the kind of theme here."
