"Comprised of songs Douglas and the Gibsons considered well suited to their road work, Darkest Hours shines in large part due to the fact that the material is more than simply well-played, but, just as importantly, also a collection of superb songs. So while they stay true to a bluegrass mantra - opening track "What a Difference a Day Makes," "So Long Mama" and "Dust" make that clear - they don't diminish their ability to simply craft standout compositions in the process".
