At a time when young country stars typecast themselves into roles that border on caricature — men brag about how rural they are to hard rock beats, women speak of empowerment with an aggressive sneer — Lady Antebellum presents an engaging anomaly steeped in sophistication and subtlety, rather than stereotypes and superficiality. The trio — Hillary Scott, Charles Kelley and Dave Haywood — address issues about relationships with an engaging honesty rare in any musical genre. They’ve been rewarded with multiplatinum, crossover success; their 2009 No. 1 smash “Need You Now” had them winning top awards at the CMAs, ACMs and the Grammys.
