2012 sophomore album from the Nashville-based Pop/Folk/Country quartet. With two sisters on lead vocals and two brothers filling out the sound, the foursome are distinguished by an arsenal of instruments and the kind of harmony only siblings can create. On The Fourth Wall, they create infectious Folk-Pop with both the buoyancy of youth and deeper spiritual themes. Most of the songs have the energy of a live show because the band polished them on the road, where they also came up with the album title. The fourth wall, in theatre terms, is the invisible wall between the audience and performers.
