1969 is considered one of the most important years in the history of rock music: it is the time of the peak and triumph of the hippie culture and “psychedelic rock” style, the time of mass festivals and wide popularization of new music.

It was then that people with an academic background began to pay attention to rock music as an independent phenomenon.

They try to bring their knowledge and unique approach to the new style. At the same time, many garage and psychedelic musicians do not like the fact that their style actively merges with pop music. In protest, they begin to play more complex and aggressive music, unusual and incomprehensible to the average person. The union of these two opposing sides (academic musicians and garage fans) creates a new style – progressive rock.
