Not from the 90s but around 2007 I think. There was a private torrent tracker called something like UGS-torrents. Where UGS stood for underground sounds. Pretty sure it was based in the UK and it focused on electronic and club music singles being released at the time from a bunch of smaller producers. Unique stuff I'm not even sure what to call the genre to be able to look for it today but a lot of it was adjacent to drum and bass, 2-step, or break beats. Super active forums with members making and sharing DJ mixes. I've been out of the scene for quite a while now but the few times I've searched for any mention of this place I've found nothing. If anyone has any information I'd appreciate it if you could share.
