First Aid Kit

from Wikipedia:

First Aid Kit is a Swedish folk duo composed of sisters Johanna (b. 1990) and Klara (b. 1993) 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. Their 2008 YouTube video cover of the song "Tiger Mountain Peasant Song" by the Fleet Foxes spread their name rapidly on the Internet, the sisters subsequently appeared alongside Fleet Foxes performing the song in a concert in Holland.

History

Starting out in 2007, the sisters sent a demo tape of their home-recorded "Tangerine" to Swedish radio on which it later enjoyed airplay in the summer. Later that year the duo signed to Rabid Records, a label co-owned by the Swedish electronic duo The Knife. April 2008 saw the release of the debut EP Drunken Trees in Sweden. The London-based Wichita Records label reissued the EP one year later, bolstering its track list with a reverent cover of Fleet Foxes' "Tiger Mountain Peasant Song" and videos of three songs performed live in a Swedish forest. During First Aid Kit's early years the duo had a collection of songs posted on the social networking site MySpace, one of which was "Cross Oceans", a re-recording of which later appeared on Drunken Trees.

2010 saw the release of their debut album The Big Black & The Blue which was followed by an extensive tour (around 100 shows) of the UK, USA, Canada, Australia, New Zealand and parts of Europe, headlining the Thursday night at the Primavera Festival in Barcelona. While playing a concert in Nashville the duo was approached by Jack White who after seeing their show requested them to record a single for his Third Man Records series. In February 2011 the duo collaborated with Bright Eyes during their performance of Lua, it was later revealed that their upcoming album will be produced by Mike Mogis.
