Ólöf Arnalds wrote "Klara" for her younger sister, in celebration of her eighteenth birthday. In the song, Ólöf asks Klara when she is coming to visit and encourages her to keep drawing. (You can find Icelandic lyrics here, and then try to decipher them using the sometimes-handy translate tool in google.)
Whenever I hear this song, I feel so encouraged; it feels like Ólöf calling all of us to pursue our youthful dreams and to live joyfully. The light sound of the charango and Ólöf's warbling voice makes the song sound like it's been played for hundreds of years.
