I'm fairly lazy / procrastinatey when it comes to things like that, but thank f*ck I yt-dlp'd it (and really not too long before it was taken down - and I don't know why and can't track down why or who made the clip).
Maybe I need to do a search to see if other people are looking for it...
And if anyone cares to know: The Mountains of Madness CD1 (I think) version Idalah Abal by John Zorn / Electric Masada, and the film clip was a bunch of still of various, mostly fringe, some quite gross/confronting art pieces. For me, it fits beautifully with the phrenetic music.
I think there's a big, thick, mental health-related line that separates an archivist from a hoarder.
Edit: OK, there are more versions the song on yt, eg: https://www.youtube.com/watch?v=swpvDV6Qvik, but that custom film-clip ain't.
Edit 2: Wrong on both counts, my search-fu ain't what it used to be. It's still there: https://www.youtube.com/watch?v=H9jk6lolne8
There was a good couple of years it didn't float to the surface of any unchanged search query.
Cool story bro, pity it makes your argument eat itself... sigh.
