Lo-fi is as much a visual and emotional atmosphere as a sound. Its best-known image is a short animated loop in a Japanese anime style: a character studying or daydreaming at a desk, a window with rain or city lights, a lamp, headphones, perhaps a cat or a cup of tea. The loop runs for hours over a live stream, so the picture barely changes while the music flows on, which suits listeners who want quiet company rather than spectacle.

The link with anime runs deep. Nujabes reached many listeners through the soundtrack of the series Samurai Champloo (2004), and the Lofi Girl stream first used a clip from Studio Ghibli’s Whisper of the Heart before commissioning its own studying girl. On the sound side, the aesthetic layers vinyl crackle, tape hiss, rain and room noise to suggest an imagined past. Researchers at Goldsmiths, University of London, have described lo-fi hip hop’s relationship with nostalgia as full of contradictions, one of several paradoxes its listeners navigate with ease.
