The music of First Aid Kit has the feel of forest folk songs, full of enchanting storytelling, and a sense of compelling, ancient mystery and, as The Guardian wrote, "They are blessed with the voices of plaid-clad angels." Their music has much in common with artists like Devendra Banhart, Bright Eyes, Karen Dalton or The Carter Family. The Swedish duo comprises sisters Johanna and Klara Söderberg (born 1990 and 1993, respectively) bu despite their youth, the pure music they create speaks of bygone times and old souls. The emphasis is on narrative lyrics accompanying playful melodies with intense, dense harmonies.
