Here We Rest is Jason Isbell's third album since leaving Drive-By Truckers, yet just his second with The 400 Unit. The musicians' growing familiarity with one another is one of the record's more salient qualities. They cover an awful lot of terrain, from the Muscle Shoals-flavored tenderness of "Heart on a String" to the funky Little Feat romp that is "Never Could Believe." Overall, the group emphasizes the folksy qualities that have always haunted Isbell's tunes. In fact, this just might be the most plaintive album the country-rocker has yet to produce. "Daisy Mae" is a total heartbreaker.
