When I was in 8th grade, our Bible class teacher brought in a video called Hell’s Bells, about Satanic influences in rock music. I only watched for one class period, because it gave me nightmares. My mother wrote a note to the teacher allowing me to go the library for that period.
Besides being scary, the video brought attention to several obscure performers that we never would have heard of otherwise. How many teenagers in 1990 were listening to Current 93, Psychick TV or Diamanda Galas?
