Following the Demozoo Slack channel exchange, here's a forum entry to follow this.
The purpose of this forum entry is to locate all the 500+ musics that entered the Blacktron Music Compo 2 (1998) (https://demozoo.org/parties/2055/).
There's an old website version at archive.org but the files themselves would have come from the FTP site ftp://skynet.stack.nl/pub/demos/bmpcompo2/. Said ftp site was note archived it seems.
If anyone has a dump of this site, please give a call. Menace agreed to mirror this on scene.org if this somehow surfaces back :)
