San Francisco’s rich and unique cultural history since its time as a gold rush frontier town has long made it a bastion of forward thinking and freedom of expression. It makes perfect sense, then, that both it and the surrounding Bay Area should prove to be a crucible for some of the most enduring and influential music of the rock and roll era. From the heady days of Haight-Ashbury in the ’60s to today, San Francisco and the Bay Area have provided a distinctive soundtrack to the American experience that has often been confrontational, controversial, enlightening, and always entertaining. Paperback, 248 pages.
