This second volume of unreleased Charlie Feathers recordings emphasizes the rockabilly king’s country roots. Though these performances are drawn from many different dates and settings, they serve as a reminder that country music was the main artery running through all of Feathers’ performances. He was a master at upending the expectations of the listener. Johnny Cash played “Folsom Prison Blues” like a man laying railroad track. Feathers turns that measured delivery elastic, and he transforms the song into something lustful and funky. On the other hand, when he was alone with a guitar, he could make an already-plaintive Hank Williams song sound even more skeletal, as he does with “Cold Cold Heart.” Feathers became a master of country because he refused to play straight country music. More than any other rocker of his generation, he understand that to get to the essence of a song you have to prod it, poke it, tickle it, or otherwise sit alone with it in the dark, as he does on the original composition “We’re Getting Closer to Being Apart.”
