It’s always seemed like a great musical concept, Oliver Wood’s rustic- modern, country- blues narration merged with Chris Wood’s unfettered jazz imagination. But all of that potential has finally been realized— with panache—on the Wood Brothers’ Buddy Miller-produced fourth studio album, The Muse. They officially became a three-piece with the addition of drummer Jano Rix, and you’d be hard-pressed to find any other trio working in roots music right now that could match their limber, musical wit. Exhibit A: “Honey Jar,” which is, at first, a churning, backwoods boogie. In a tart voice, echoing the vocal timbre of pre-electric Delta bluesmen, Oliver sings about a poor fool putting himself out there for the sake of desire. Then, the guys coast to a stop and fall into a boozy shuffle, with Oliver leading a surreal call-and-response: “The fool is dreaming, there’s honey dripping off of the spoon where his heart should be.” No two tracks feel too much alike, which is a testament to the brothers’ elasticity, but every single one stays in the sophisticatedly down-home pocket.
