First Aid Kit is a Swedish folk duo, composed of sisters Johana and Klara Soderburg. They have been composing since 2007 and feature a very stripped down style focused around harmonies. The attached video is from a featurette where they preformed some songs in the woods behind their home. This song specifically is called "Our Own Pretty Ways" and features heavily folk influenced lyrics. Among their influences are the ever influential Fleet Foxes. The song is heavily focused around the vocals and the piano and guitar, while repetitious, subtly enhances the vocal performances rather than detracts from them. Personally, the song calls up warm imagery and features enough pitch changes to and vocal inflection to keep one interested while still being relaxing.
