In 1965, Jim Marshall (1936–2010), complete with camera, moved from New York City back to the place where he grew up, San Francisco; he settled on Haight Street. On the West Coast, the counterculture was questioning everything. Men were letting their hair grow past their shoulders, women were tying theirs in bandannas, and amid the weed and the cobblestones, the prim full skirts of the 1950s were laughably old hat.

Rock music propelled it all, and Marshall was in the middle of it. Just a few blocks away, Longshoremen’s Hall hosted concerts, and the Fillmore Auditorium, at the corner of Geary Boulevard and Fillmore Street, became the place where Bill Graham, a young German-born impresario, began promoting shows. Two blocks north, the Panhandle stood at the neighborhood’s heart. Most importantly, at 710 Ashbury Street, the Grateful Dead lived in a communal house for 18 months—from September 1966 to March 1968.
