Janis Joplin's screaming soulful voice in many ways is a personification of the Flower Power Era (along with Jimi Hendrix, Eric Burdon, Grace Slick and many others). She came to symbolize energy of the Psychedelic, Haight Ashbury, love beads, love ins, free love, flower children, black light posters and incense, expansion of consciousness, spiritualism soaked in the unusual drug idealism of the late 1960's. It was a time of bright hope and optimism and the shedding of many social-psychological-sexual traditions that went sour.
