Sisters Johanna and Klara Söderberg have found their sweet spot at the intersection of the renewal in Nordic pop and the thriving new folk scene in the United States. These Swedish artists, who craft stunning folk melodies and vocal harmonies as pop as a meteor shower, have dreamed since their start in 2008 of a mythical America composed of enchanting country ballads, desert vistas burned by a thousand suns, and hospitable shores with striking features. Mesmerizing when their voices come together into a single entity, this duo with world hits already in the bank ("My Silver Lining”, etc.) have revealed albums with incredible aesthetic ambitions: The Lion’s Roar, for example, and Ruins, a fourth opus steeped in painful melancholies and recorded with Peter Buck (R.E.M.) and Glenn Kotche (Wilco). With sweetness, beauty, and an admirable honesty, First Aid Kit bandages wounded souls.
