Those already familiar with First Aid Kit may be shocked by the portent in the title of their second album, The Lion's Roar. For a duo so built on understatement, it's a statement of its own volition – words which suggest something bigger, bolder, and stronger.From the reflections of Blue, the influence of the Swedish sisters' dream producer Mike Mogis (best known for his work with Bright Eyes) becomes apparent. Still pared down but clearer, the sweet mimicking between bass and xylophone feel more ominous than decorative.Johanna and Klara Sodenberg's close harmonies charm unaffectedly, pitched in the mix like the faint voices of songbirds echoing through a woodland scene. And, lyrically, there's a mix of gloom and lilt in the perfect order and proportion; in spite of Conor Oberst's involvement, there's no stagnation, no lack of positivity and certainly no halting moments of impenetrable self-reflection.
