Welch and fingerpicking genius cohort David Rawlings make ancient-sounding songs that glint with modern dread. After ''O Brother'' hit the soundtrack jackpot, ''Time (The Revelator)'' moved Welch's stylistic clock forward; on Soul Journey she further subverts her Walker Evans-style image -- what, no retro housedress?! -- with aching songs about restless daughters that reference classic soul and pastoral psychedelia. And her smoky Appalachian porch moan has never sounded deeper, realer, or sexier.
