First Aid Kit are a Swedish duo comprised of sisters Johanna and Klara Söderberg, whose close vocal harmonies and woodsy, folk-influenced songwriting take influence from the likes of Fleet Foxes and Joanna Newsom. Hailing from Enskede, a southern suburb of Stockholm, the teenaged siblings began composing songs in 2007. The home-recorded "Tangerine" enjoyed airplay on Swedish radio later that summer, and the debut EP Drunken Trees expanded the duo's audience upon its release in April 2008. The London-based Wichita Records label reissued the EP one year later, bolstering its track list with a reverent Fleet Foxes cover and three additional songs performed live in a Swedish forest. The duo then set to work on a full-length album, readying its release for September 2009. ~ Andrew Leahey, All Music Guide
