Done and doner

Kurt Andersen talks with Morgan Neville about his documentary that focuses on an Orson Welles film that was completed long after Welles died. Maria Schneider’s album “The Thompson Fields” took a circuitous path, and she discusses it both as it’s being conceived and a year later, when it’s in the can. Neuroscientist Heather Berlin tells Kurt how the creative brain gets revved up — and how the brain helps to focus and complete projects. And how the band School of Seven Bells finished an album when a key member tragically wasn’t there to finish it with them.
