Beginning
Psychedelic rock was the style of music popular in the late 1960s that was largely inspired by hallucinogens, or so-called mind expanding drugs such as marijuana and LSD (lysergic acid diethylamide), that reflected drug-induced states through the use of feedback, electronics and intense volume.

Emerging from the 1960s psychedelic rock became the soundtrack for the wider cultural exploration of the hippie movement. Initially centred on the West Coast of the United States, psychedelia soon spread from San Francisco Bay area to the rest of the country and then to Europe to become the major rock phenomenon. Established rock bands also began to introduce psychedelic elements into their music, notably the Beatles with such albums as Revolver (1966) or Sgt. Pepper’s Lonely Hearts Club Band.

Soon the psychedelic experience of sharp rock sounds became the musical soundtrack for a new youth culture, the hippies. The Hippie movement and the new Beat Generation are immediately associated with the rock paradox. The peculiarity of the hippie movement of the late 1960s in the USA tied up with Vietnam War service and anti-Vietnam War protests, the Civil Rights Movement, and sexual liberation, which were noticeable in the rock scene not only in the USA but also in Britain.

The young generation in the fifties desperately tried to build a new life style breaking with all old rules and taboos in order to followed the intimate desire of their wildest dreams. The songs from the film soundtrack like "Born to be Wild" by Steppenwolf, the Byrds and their "I Wasn’t Born to Follow" or the Jimi Hendrix Experience's "If Six Was Nine" proved to be key connectives between black funk and psychedelic rock. They are just a few reflecting the idea of psychedelic rock’s influence that was evident in many film genres of that time. And they do not just serve for illustration of the film scenes. There is a certain relation between the music and the scenes, which are appealing even more strongly because of the music and the texts of the songs.

Dusk of PR
This popular kind of music created a new ideology that has been articulated everywhere and was commercially packaged by emergent record companies. The American film company Warner Brothers took inspiration and the opportunity to make a lot of money by depending on the music business. The new generation in the USA had grown up to the sounds of the mass-cultural power of rock and roll. The immediate consequence was the power of pop music which next to a new way of self-expression in poetry richly decorated in serious and sharp sounds served for a social voice of protest.
