I remember in the late 70's early 80's having to burn all my records. My Mother went to a church that played songs from different bands backwards so we could "hear the evil" in the music. My Mom freaked and made me burn them.
I find it interesting that bands do this. I mean how many people really think to listen to them in reverse? Other than a very few.
I am going to have to check mine out. Some are a little freaky.
Do you think that these messages can get to the subconscious?
Oh yes, I remember the record burning! Many parents were forcing their kids to burn their records or taking them away from them. I had my records taken away from me, but that was because I was caught smoking! lol Not because of backmasking. I think when it comes to backmasking, you hear what you want to hear, or whatever you expect to hear. Some bands do it purposely while others do not. I don't think it can get into the subconscious either.
