The Civil Wars" self-titled sophomore album, which was No. 1 on the Billboard 200 chart last week, tells the story of a duo in turmoil. Recorded earlier this year amid building tension between the bandmates Joy Williams and John Paul White (they abruptly halted a European tour last November because of "internal discord and irreconcilable differences of ambition"), the album is rife with allusions to heartache and regret, providing subtext for the two singer-songwriters" own conflict. This new video, an exclusive behind-the-scenes look at recording the track "Sacred Heart," captures a playful, if fleeting, moment of armistice. Williams wrote the song in a flat in Paris and sings it in French - she's proficient in the language, though she admits that a friend helped with the lyrics - but trademark harmonies and romantic, acoustic arrangement are intelligible to all. For fans, the sight of Williams and White joking and laughing in the video offers a welcome reminder of the pair's promising past, and perhaps a hint at their future. "I think there's been assumptions made that the band is over, but the reality is that John Paul and I have yet to talk about that," Williams said in a phone interview earlier this month. It took the both of us to break it down, and I think that same energy is also there that if we put our heads together, we could meet in the middle and be an even stronger duo for it.
