The following is an excerpt from the Wikipedia entry for backmasking.
"The 1983 California bill was introduced to
prevent backmasking that "can manipulate our behavior without our
knowledge or consent and turn us into disciples of the Antichrist".
Involved in the discussion on the bill was a California State Assembly
Consumer Protection and Toxic Materials Committee hearing, during which
"Stairway to Heaven" was played backwards, and William Yaroll testified.
The successful bill made the distribution of records with undeclared
backmasking an invasion of privacy for which the distributor could be
sued. The Arkansas law passed unanimously in 1983, referenced albums by
The Beatles, Pink Floyd, Electric Light Orchestra, Queen and Styx, and
mandated that records with backmasking include a warning sticker:
"Warning: This record contains backward masking which may be perceptible
at a subliminal level when the record is played forward." However, the
bill was returned to the state senate by Governor Bill Clinton and
defeated."
he success or lack of success of the attempt to regulate back-masked
content distribution doesn't address whether the claim made about it was
valid or not. I don't know if there was any awareness at the time that
the "Stairway to Heaven" song presented as evidence wasn't actually the
result of back-masking. That song's hidden message programmed into the
subliminal channel without any manipulation of the recording. However,
what I consider as evidence of influence is the content they brought to
the attention of the court and to the public. It was satanic and
evangelistic in nature. From a biblical perspective, the conclusion
drawn from the facts was that the songs with messages of that nature
"can manipulate our behavior without our knowledge or consent and turn
us into disciples of the Antichrist". Can the content influence us, even
though it has to be reversed to be understood by the conscious mind?
Some, like Bill Clinton, say no. Those who want to know the truth, have
nothing to hide and are not afraid to think for themselves tend to
disagree.
If the channel isn't listened to on some level and its messages
received with some effect, how is that music with content on this
channel such as found in Led Zeppelin's "Stairway to Heaven," Black
Sabbath's "Iron Man" and Mercy Me's "I Can Only Imagine" are so
passionately embraced? Think about it. There's something about this
music that appeals very directly to a person.
If there were no power to influence, would Aleister Crowley have
expressed an interest in leveraging the use of this channel and
encouraged the exercise of its use through his books on magick? No!
Would the recent Olympic ceremonies from Beijing employ subliminal messaging
ranging from deliberate backmasking to a wide variety of visual
elements if those funding the effort with exceedingly deep pockets
didn't expect to realize some significant benefit? No! Would demons
bother to hijack this channel, which they clearly do, if there's no
listener and no influence brought by it? Really, why would any honest
person think the backwards messages means nothing. When you consider
what these messages are and the context in which they appear, only one
conclusion can honestly be drawn. I think those who attempted to bring
the awareness of the existance of these messages to the public's
attention exercised good judgment when they declared the nature of the
threat. I have seen a large enough sampling of the messages presented on
this sub channel of communication to see for myself that many of the
messages are demonic, and that the intent is to bring forth worshippers
of Satan in the spirit of antichrist who will receive the mark of the
beast!
Subliminal messages are defined as communication that occurs on some
level below the threshold of consciousness. You don't have to look far
to find circumstantial evidence indicating these are fundamental to the
human experience. Some who depend upon this reality are called marketing
experts. Right? Subliminal messaging isn't limited to the insertion of
occasional pictures of popcorn and soft drinks into movies. While it can
consist of pictures and words the craft is really in the skillful use
of symbolic content, of colors, shapes and sounds, of massaging the
imagery to elicit targeted responses. Consider Nissan, which tags their
car models with certain letters. They had the Sentra SE, they had the
Sentra SX, the EX and the XE. In the UK, Nissan sold the Almera SXE.
Now, just where do you think they were going with that?
When someone is "good at sales," that means they're able to
effectively manipulate the behavior of others. Do you think sales are
made strictly on a conscious level? The reality is far more complex than
that. By every means possible the feelings and emotions are plied. The
thing is, we're just so accustomed to this interaction we don't even
acknowledge it. It's just "normal," and how it's always been. The
backwards speech channel has always been part of our experience, and we
just haven't been aware of it. We transmit. We receive. If no one's
listening to the subliminal, why would anyone spend money on sales and
marketing as it now exists?
