That's about when I got into it too! I got a lot of the early 90s stuff when I started working at a record store in 99 and I found that the late 80s/early 90s black metal scene was a very strange place lol
I read some interviews about it, it was supposed to be a serious video. The band members said the production company only gave them 2 hours on the day of shooting and then kind of made fun of them later. They were pretty pissed at the time. If you look into the history of black metal in the early 90s they really all took it way too seriously lol
