Stumbleine is the solo project of UK-based producer Peter Cooper, known for blending ambient shoegaze with dreamy lo-fi to create lush, emotionally resonant soundscapes. Since his debut in the early 2010s, Stumbleine has become known for crafting immersive, nostalgic tracks that feel like distant sun bleached memories. Often submerged with bittersweet vocals that dissolve into fragile melancholic textures, Stumbleine's sound offers a quiet escape into a world of haze, warmth, and understated beauty.

A founding member of post-dubstep pioneers Swarms, other projects also include the downtempo dreamscapes of Hope Stands Alone and the club driven sounds of Polly Is Lucid
