Season of the Witch: Enchantment, Terror, and Deliverance in the City of Love by David Talbot:
The Haight was still just a scruffy, fog-bound neighborhood when Marilyn moved there, with Russian bakeries where you could buy piroshkis. But the fairy dust was already floating overhead. The year after she settled in the Haight, a young band called the Grateful Dead moved into a big Victorian across the street at 710 Ashbury. Janis Joplin rambled around the neighborhood in her scarves and boas, swigging from a bottle of Ripple with her bandmates, and Marilyn would bump into her at Peggy Caserta’s clothes store on Haight. They all became friends. Nobody was a celebrity in those days. The neighborhood thought it owned the bands. Everyone took care of one another.
