Psychedelic rock

"There is no one song that “started” the psychedelic rock movement of the 1960s. It was a natural evolution and a response to what rock music had delivered thus far."

"The hippie movement was about a lot of things — drugs, love, peace, anti-establishment, anti-war — and at the forefront of the movement was the music, psychedelic rock."

"Psychedelic rock is [...] rock's most inventive [sub]genre. Whether or not psychedelic drugs played a role (and as many musicians say they've used them as not) psychedelic rock has consistently charted brave new worlds that exist only in the space between the headphones."
