Ken Burns has churned out some spectacular documentaries on historical subjects — subjects that changed how we think as a society. Call him old school, but there’s no denying his mastery of the genre. Hell, the man even has a visual technique named after him. This time around Ken is tackling one the most devastating environmental disasters in our nation’s history, The Dust Bowl. In this segment, by Sarah Klein and Tom Mason, Ken shares with us what he feels makes a normal story become a great story. “Story is manipulation…but I hope I achieve a positive manipulation.” PBS will air Ken’s new four hour documentary this coming November.
