You get the sense that Will Kimbrough has gained his self-knowledge in ways that make him a little uneasy, and that seems appropriate for the marriage and love songs on his new full-length, Sideshow Love. The longtime Nashville rocker and ace session guitarist writes pungently about the way media images can distort the values of real-life marriage in the record’s “Home Economics,” which employs a ricky-tick folk-blues riff. Kimbrough plays “When Your Loving Comes Around” as a modified Excello Records-style shuffle, and his canny sense of rock, soul and blues form provides structure along with plenty of subtly turned guitar licks. Kimbrough’s songs describe how outside forces can disrupt love and romance — in the title track, paparazzi harass Kimbrough and his true love, so they have to wander from “Yazoo City to Timbuktu” to avoid publicity’s glare. Elsewhere, Kimbrough eschews “slash-and-burn techniques” in “All We Can Do Is Love,” which sums up his message nicely.
