Book excerpt: Legendary rock showman Dave Graney takes us on a journey about self-discovery. As a young man fired up by punk rock he sets off on a road-trip from small-town Australia, outside of life and looking for a way in. When he loses the map Graney discovers his groove, then twists and turns through three decades as a working artist. When Graney takes the wheel, you don't know where you'll end up - or if you'll get there safe. This ain't no standard rock'n'roll trip; it's an education. This is Graney up close, out there and on his game. Turn it up loud.
