Yeah I remember 15+ years ago before channels like that if you wanted to find obscure bands that had only released like one in the 90s and that was it, you either had to find blogspots with Mediafire/MegaUpload links, or torrents of some kind like Soulseek. I preferred the blogspots because the good ones would usually have the album/demo art and a little bit about the band to get you interested.
That’s how I found Catacomb and Immortalis and a bunch of others but thankfully because of the amount of people that use YT, some bands can blow up in the algo which is great. That Catacomb upload having half a million views is nuts. It’s nice to see old bands get recognition like that especially since I’ve been on a big death/doom kick lately:
