As promised, I'm going to take a closer look at the process of backmasking in recording music.
The first band to gain fame for backmasking was Judas Priest. They went to court over the matter, with conservatives alleging that hidden messages in their album "Stained Class" convinced a couple of teenagers to commit suicide. The so-called subliminal influences were phrases such as "Do it", "Fuck the Lord, fuck all of you" and the like. (Corbin & Ganger) However, when the tapes were actually reversed in court, not a single instance of these suicidal influences could be found. One song included the phrase "I asked her for a peppermint/I asked her to go get one", which I daresay does not make me want to kill myself. Besides, during the trial no evidence of the effect of backmasked messages on the human mind was ever presented, because the prosecution couldn't acquire any. Lately it has actually been proven that it is impossible for a backwards recorded message to have any kind of influence over the listener. (Moore) Fortunately for heavy metal lovers out there, including me, the judge decided that while messages might have been present in the recordings, they were unintentional, and had no effect on the two victims whatsoever. This was not the victory the band had hoped for, but they managed to hold the line for all other bands that once have snuck in secret messages in their music. If they would've lost the case, the floodgates for an invasion of lawsuits against bands and media in general would have opened, unleashing what could have been a devastating attach on the industry.
Thankfully, both their lawyers and the band held their own against the accusations, and music of all types continues flourishing every day.
