It was taken from a horror film titled: Whispers, film adapted from the horror master writer Dean R. Koontz. Directed by Doug Jackson in 1990. (This is what the YouTube comment said anyway)
Never seen it myself.
The album used to be a bitch to find until it got reissued. Went for in excess of £50 on Amazon. Due to this I had one song off it downloaded called "Before the Dawn" which I used to listen to all the time, but my conscience wouldn't let me download the rest of the album haha. I got burnt out on that song and "Unholy Prophecies" is now probably my favourite on it. Every track is killer, though. Mixing the buzzsaw sound of Entombed and Dismember, but with an awareness of the developing black metal scene in Norway, there's really nothing else like it for the time period (that I'm aware of anyway).
