LADY ANTEBELLUM With the success of Sugarland and Little Big Town, Nashville is primed for another male-female group to continue breaking up the traditional mold of solo guys and gals. Lady Antebellum has got the goods to be that band. The three-part harmonies, hint of grit, and appealing contemporary country sound of the group's first single, "Love Don't Live Here," bodes well for the as-yet-to-be-titled debut from Hillary Scott, Charles Kelley, and Dave Haywood. Before their disc, produced by Dixie Chicks and Little Big Town knob-twiddler Paul Worley, drops in April, the trio will hit the road as an opening act for Martina McBride.
