This trio have never actually strayed all that far from their roots in the deepest Delta, but on this disc, the Allstars really snake those tributaries deep into the dark, fertile soil of their home state. Naturally enough, that means paying a great deal of attention to the region's indigenous blues strains -- as on the purposefully murky, electrified take on Charley Patton's "Mississippi Boll Weevil." On that track, tendrils of Luther Dickinson's guitar creep through the shuffling rhythms like kudzu growing up the side of a shotgun shack. A similar dirt road vibe permeates "Bang Bang Lulu," a hill country traditional that's given an extra dose of moonshine-fueled libidinousness by new lyrics woven in by Dickinson and his drummer brother Cody. The Allstars cast their net past the reach of the juke joints this time around, however. On "No Mo," for instance, they bring in Memphis rapper Al Kapone, whose languid drawl combines with Dickinson's slide guitar to make a stingingly fiery sonic gumbo. Lucinda Williams brings more of a slow burn to "Hurry Up Sunrise," a closing-time duet that recalls the classic pairings of Loretta Lynn and Conway Twitty. Concise, flab-free, and more back-to-basics than anything the Allstars have mustered since their debut, Electric Blue Watermelon lays a stoned soul picnic that'll set those synapses ablaze.
