Speaking with … Joe Jackson

Twenty-five years after Joe Jackson, Gary Sanford, Graham Maby and Dave Houghton began recording “Look Sharp,” which was released in 1979, the musicians have reunited for “Volume 4” (Restless) and a tour that brings them to Chicago this weekend. Phoning from New York, quirky singer-songwriter Jackson talked about the strains of touring, his favorite books and how he’d fare as a new artist in today’s looks-obsessed market.
