This is an unsuccessful combination of a travelogue, a history of country music, and an analysis of current trends in Americana. The historical portions are thinly researched, the analysis is at best trite and unoriginal and at worst confused, and the travel writing is a failed attempt to channel the mystique of the American road. Everything is in a blog style that is far too lightly edited. Despite Ms. Petrusich's clear affection for the music, she has nothing interesting or new to say about it. The only crumbs of insight come from artist interviews and quotes from other authors. There is plenty of great writing about country music and its history; off the top of my head, recent enjoyable reads include Havighurst's Air Castle of the Sky, about WSM; Colin Escott's Hank Williams bio; Gura's America's Instrument, about the banjo; and No Depression, in its magazine, anthology, and online forms. Check those out instead.
