obscure community, music
There's a user on Youtube called GoldPile who has reuploaded psybient mixes by someone called Spacemind, and a small but persistent community seems to have formed around these mixes, with people wondering for many (9+) years now where Spacemind has gone and whether they'll ever return, and GoldPile having continued the style of mixes, but they now also haven't uploaded for a couple of years.
Every few months to years, Youtube recommendations send me back to one of these mixes, and they are still so good, and there are still people in the comments wondering where they went.
