NEW YORK TIMES: Resolutely traditional in approach, Charlie Louvin and his brother, who died in an automobile accident in 1965, were proponents of the high, lonesome sound of the southern Appalachian Mountains, where they grew up. Some of their best-known recordings were updates of foreboding antediluvian ballads like “In the Pines” and “Knoxville Girl.” Other material centered on the wholesome likes of family and religion, including “The Christian Life,” an original that later appeared on “Sweetheart of the Rodeo,” the landmark Byrds album featuring the singer Gram Parsons. Alternative rock acts like Elvis Costello and the band Uncle Tupelo (which recorded a version of their cold war plaint “Great Atomic Power” in 1992) also fell under the duo’s sway. MORE
