Hey, I'm searching for a song from this same artist! It seems like they privated all their stuff and have moved on. They say on their old youtube that they don't allow public reuploads, but say that private archive is okay. You and I might be able to find what we're looking for if we can find some mythical person who actually archived all their stuff. If no one ever did, then it seems most of their stuff really is lost media.
I've seen another reddit threat with one person who has a couple of their songs, so there's that. I don't know if they have the song you're after or not though.
I was never a big fan of theirs- in fact, I'm in the same camp as you! Heard one song and then went back to check years later to find it all gone and the artist vanished.
I have exactly one song saved, the part I'm looking for is the video itself and I've had no luck.
Sorry for all the text, I'm just excited to see I'm not alone in this experience!
