Literature and multimedia-loving San Franciscans will enjoy Wednesday's Pop-Up Magazine, a night of live presentations from contributors to Wired, All Things Considered, Harper's, et al. Award-winning artists and authors on stage at the Brava Theater will include New York Times Magazine contributors Michael Pollan and Peggy Orenstein; The Kitchen Sisters, Davia Nelson and Nikki Silva; and photographer Todd Hido. Lest you be upset that the Pop-Up Magazine is a one-night only event, This American Life Live will be shown at theaters around the country on Thursday to provide your smart independent culture fix.
