Still in their teens, Swedish duo First Aid Kit comprises sisters Johanna and Klara Söderberg. They produce a sound that belies their tender years and purvey a collection of spine-tingling songs that have drawn comparisons to everything from Joan Baez to Bon Iver. Having wowed a handful of small UK festivals this summer it’s apparent that they’re on their way to patching up everybody’s wounds with their enchanting forest folk.
