If there's an Americana A-Team, Will Kimbrough is an all-star outfielder with a cannon for an arm. Guitarist of choice for Rodney Crowell, Todd Snider and Josh Rouse, Kimbrough has the lyrical knack and flat-picking chops to score big in Music City while barely recognizing the rules of the game. His latest release, the pithily titled (EP), finds him recording at home with just harmonica, guitar, cello, rag-tag percussion; hard luck and a harder jones for love supplant the strident politics of last year's Americanitis. "It won't work this morning, I can't punch in," he sings on "Horseshoe Lake," alluding to both record- and soul-making. "There's too many questions under my skin." Through all the offhand interrogations and quietly searching country voice, Kimbrough's Alabama-blues bloodline runs straight and true.
