It's hard to tell where the traditional ends and the original begins in the music of Eilen Jewell, a sweet-voiced young singer who steeps her material in the hard times of old, reviving the stories and musical styles of the Depression.  On her own "Rich Man's World," she casts herself as a "lonely rambler girl" while conjuring comparisons with Gillian Welch. Another original, "In the End," sounds uncannily like Lucinda Williams, while a revival of Eric Andersen's train-hopping "Dusty Boxcar Wall" and the double-entendre blues of the traditional "If You Catch Me Stealing" reinforce the sense of Jewell as a musical throwback to a time before she was born.  Yet there are timeless pleasures here as well: a bittersweet reading of Charlie Rich's "Thanks a Lot," an understated, harmony-laden rendition of Bob Dylan's "Walking Down the Line," the sultry cantina twang of her original "Too Hot to Sleep." When the musical arrangements aren't generic Hot Club and the songs seem more like role-playing, Jewell sounds like a singer with enough promise to develop her own identity.--Don McLeese
