The document summarizes the emergence of modern rock music in San Francisco in the late 1960s. Key developments included the rise of album-oriented rock (AOR) formats featuring bands like the Grateful Dead and Jefferson Airplane on FM radio. The psychedelic rock scene in San Francisco was driven by the counterculture of the time, popularization of LSD, and venues like the Fillmore West. Festivals like Monterey Pop in 1967 helped launch the careers of many San Francisco-based bands and attracted major record label interest.
