Jason Isbell likes to wander. When the songwriter stops in New Orleans, he likes to do some people watching, stop at Faulkner House Books, and then there was that time last year he performed among a dozen New Orleans artists and Bruce Springsteen, John Fogerty and Mavis Staples in a salute to Dr. John.?
