"Rock has always been the Devil's music"said David Bowie to Rolling Stone magazine on Feb 12, 1976.
It has been said that Mick Jagger, lead singer of The Rolling Stones, claimed that Anton LaVey (founder of the Church of Satan) helped inspire their music.
Blues genius Robert Johnson is rumoured to have made a pact with the Devil to become the greatest blues artist of all time provided he agreed to die young.
Led Zeppelin guitarist Jimmy Page is well known to have had a penchant for dark occult teachings such as those of Alistair Crowley.
Here is a picture of the Beatles doing the 666 and devil horns signs with their hands:
Bernie Taupin, songwriting partner of Elton John, said of the latter:
"Elton John's home is laden with trinkets and books relating to Satanism and witchcraft."
Most modern MTV music strikes me as satanic in both sound (stimulating the reptilian brain rather than the neocortex) and visual representation with often perverse sexual overtones (e.g. Katy Perry's California Gurls music video) and questionable lighting techniques, not to mention allusions to dark occult rituals such as in Lady Gaga videos.
Still from the appalling California Gurls video
Speaking of Katy Perry, she apparently said
"When I started I wanted to be like the Amy Grant of music, but it didn't work out, so I sold my soul to the Devil." - Katy Perry
Rock'n Roll of course was an American term from the Southern States meaning sexual intercourse.
Here is rapper Jay Z doing the all-seeing illuminati sign and his label is called Rockefella Records, presumably in reference to the alleged 'illuminati' Rockefeller dynasty.
Influential songwriter Bob Dylan said in interview that he owed his success to
"the Big Guy who runs the show"or something like that. I think he meant Satan, not God.
AC-DC's album Highway to Hell is said to have been used in a military context.
Miley Cyrus videos have been linked to illuminati MK Ultra ritualised child abuse and bands like Muse and Immortal Technique have made explicit reference to MK Ultra.
Still from Muse's The Handler video which references Project Monarch for those in the know of the symbolism and the realities of that darkest of corners
Disney has been found to insert sexual subliminal messages in some of their kids movies - this can easily be verified on youtube - and Walt Disney himself has been claimed to be a practicing satanist.
In any case the internet is replete with deep and sometimes valuable analysis of the subversive and lascivious symbolism present in modern popular culture and music.
A good source for this kind of analysis is vigilantcitizen.com.
For hidden meanings and messages in mainstream cinema jaysanalysis.com has a great film analysis section that draws on profound esoteric knowledge.
Of course, none dare call it a conspiracy.
Addendum - Of course there are countless more examples of the link between Rock music and Lucifer's influence but sometimes this can be possibly seen as the fruit of a rebellion against the outmoded and hypocritical Christian moral worldview such as one finds in Conservative households in America which can be a great fetter on creativity. I myself have been fascinated by Lucifer in the past (see post Lucifer, Light Bearer).
