Grayson Capps’ fifth studio album, The Lost Cause Minstrels, finds the Mobile, Alabama-based singer-songwriter coming of age. But that doesn’t mean his often unholy tales of the Southern Gothic have lost any of their sting. Quite the contrary, Capps’ Tao-tinged philosophical musings revealed inside songs shuddering with spit, stomp and snarl are as potent as ever. Look no further than “Highway 42,” “No Definitions” and “Rock N Roll” to hear that Capps cedes no quarter. It’s just that this time his bark and bite is more accepting of the unanswered questions mucking up the universe. And yes, occasionally, even a celebratory mood prevails like the horn-fueled romp “Ol’ Slac,” an ode the rebirth of the Mobile, Alabama Mardi Gras, or “Coconut Moonshine,” a character sketch based on Mr. Jim who inhabits the hallowed roadside barbecue joint in Ocean Springs, Mississippi. Two rare but classic American roots’ numbers are born again here, as well: Taj Mahal’s country-blues paen “Annie’s Lover” and Richard Rabbit Brown’s jaunty “Jane’s Alley Blues,” (the original recording preserved on Harry Smith’s Anthology of American Folk Music).
