Neither as Stax-era ersatz as Duffy and Amy Winehouse or as Starbucks-smooth as Norah Jones, retro-soul chanteuse Diane Birch lingers somewhere in the middle with her piano-laden torch songs, more in line with the mellow and only occasionally feisty moods of Carole King and Carly Simon than with any of the current crop of 60s obsessives. Although her songs are polite enough to attract both pretty young things and their moms, the preachers daughter has a bluesy voice thats slightly too raspy to suggest clean-cut church livin'. On her debut, this yearsBible Belt, it comes surrounded in appropriately vintage grooves and sepia-toned shadings, ranging from the late-night lament of Fire Escape to the jaunty finger-snapping pop of Valentino.
