Somewhat related: The Youtube algorithm also recently lead me to this Japanese musician I wasn't familiar with:
(Ryo Fukui - A letter from slowboat)

Ryo Fukui has been very popular for a long time with the /mu/ sort of crowd. There's a group of artists (ryo fukui, animal collective, neutral milk hotel, the antlers, mount eerie, destroyer, the avalanches, gsybe, etc) which are basically a clique in the music recommendations graph. Although they aren't very close to each other genre wise, they are safe bets as a recommendation for anyone who listens to any music in the /mu/core 'genre'.
Yeah I came on to leave a comment about Ryo Fukui. He unexpectedly popped up in my feed a few years ago. I have no idea why they suggested it, but I enjoyed him. (Jazz trio). When I read the comments everyone was saying, “dunno why I landed here but this is good”.
Have had similar things with topics like billiards, lock picking lawyers, and now ex-convicts. (Shout out to OG Badger and Wes Watson — CHICKEN ON THE BONE)
It goes even deeper - the Youtube algorithm recommending the likes of Ryu Fukui, Taeko Ohnuki and others has led online music aficionados, who knew about these artists before their decades old music gained renewed popularity with millions of views, to term them "YouTube-core". For example, I had a physical copy of one of Ryo Fukui's album around 2014, before it took off (or perhaps even before it was uploaded) on YouTube. The music is, of course, excellent, but it's funny how these things come around.
