In 1980, Gordon Ball adopted a phrase from the Irish poet William Butler Yeats, "technical sincerity," as a touchstone for his first-person filmmaking. In the next iteration of our regular Salon series, the filmmaker will arrive in San Francisco to show and discuss six films from his body of work that exemplify this mode. This event follows a reading Ball will be doing at the legendary City Lights bookstore from his collection On Tokyo's Edge on Wednesday, May 17 at 7:00 PM.
