Peter Richardson on how Rolling Stone shaped a social revolution … at least for a while

Peter Richardson, author of the new book "Brand New Beat: The Wild Rise of Rolling Stone Magazine," discusses the pioneering music magazine's San Francisco decade — between 1967 and 1977 — when the Bay Area's counterculture reshaped music and the journalism that covered it. From Haight-Ashbury to the Fillmore, Hunter S. Thompson to Annie Leibovitz, the magazine documented a social revolution while simultaneously creating it.
