Being the offspring of famous musicians may come with some baggage, but that doesn’t seem to bother the members of Folk Uke: Amy Nelson (daughter of Willie Nelson) and Cathy Guthrie (daughter of Arlo Guthrie). They stand on their own merits by offering charmingly off-kilter material and not taking themselves too seriously. Their mellow country-folk features honey-sweet vocal harmonies and subdued strumming (Nelson on guitar and Guthrie on ukulele), but the duo really makes its mark with humorous and often absurd lyrics and entertaining tongue-in-cheek tales. “Nobody Blues” is about finding a severed foot along railroad tracks, while “Quattro Momento” details a sordid bachelor party from the perspective of the soon-to-be bride. The dark satire of “I Miss My Boyfriend,” with guest Shooter Jennings, elicits a wince and chuckle at the same time. Along with its original compositions, the duo does a good cover of Harry Nilsson’s “He Needs Me” to round out an enjoyable second release.
