There is limited widely documented information about 8belial, yyy891, and JOHNNYFUU as a collective or as individual artists; they are names associated with underground electronic and experimental music scenes, often appearing in online platforms and independent release contexts. The aliases suggest activity in the internet-era DIY electronic sphere, drawing on genres such as glitch, ambient, IDM, and experimental beat-making, with production techniques that emphasize textural sound design, lo-fi aesthetics, and digitally manipulated timbres. Their work is characteristic of bedroom producers and netlabel communities from the 2010s onward, where artists circulate short-run releases, remixes, and collaborative tracks primarily through streaming platforms and file‑sharing networks.
