Set the Night on Fire: L.A. in the Sixties is a movement history by Mike Davis and Jon Wiener published in April 2020. The authors combine archival research and personal interviews with their own experiences in the civil rights and anti-war movements to tell the story of this transformative decade. The book's purpose is not to present a comprehensive history of 1960s Los Angeles but to dispel the mythology surrounding this era and replace it with the neglected history of the populist social and cultural movements that shifted power away from an entrenched elite and opened up opportunities for radical egalitarian change.
