Location, location, location. Not only is it important in real estate, but it also helps the recording process. Well, at least it did for singer/songwriter Jimbo Mathus, known for his role in Squirrel Nut Zippers. For his ninth album, Dark Night of the Soul, Mathus visited Dial Back Sound Studio in Mississippi for nearly a year, recording bits and pieces of songs as they came to him with the help of Fat Possum Records’ Bruce Watson, who operates the studio. Together, Mathus and Watson gathered 12 tracks that cover the spectrum of Southern music: blazing rock jams, rollicking country tunes, and heartfelt blues, all featuring Mathus’ homegrown twang.
