I really need help to find one track or my brain will explode!

Its from ...i don't know the age, i was a child, i this the middle of the 90th.
I recordered it on cassette and i only remember few things: first it was very very dark deep trance track, i remember guy from the radio explaining the cover of cassette that was something like ''picture of the man and from his mouth was coming out a wolf jaw''
In that track was constantly repeating man who was screaming and while he screams there was sound like skin tearing and stuff like that.
