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.

Ann Carlson discusses her new book "Smog and Sunshine: The Surprising Story of How Los Angeles Cleaned Up Its Air."

An expert in environmental law, Carlson chronicles the decades-long battle that transformed the air from toxic to breathable, and what today's rollbacks threaten to undo.
