I wasn't a Christian then but was somewhat very curious about the whole hoo-ha thingy of christian groups protesting against satanic cults & pop groups...
Actually a number of those alleged pop groups were my favourites even though I wasn't much of a music fan. Below are some disturbing (scary to some) acronyms found on the internet:
Backmasking is a recording technique in which a sound or message is recorded backward onto a track that is meant to be played forward. Backmasking is a deliberate process, whereas a message found through phonetic reversal may be unintentional.
