Slave to her creative drive and wild fantasies, at 44 she’s like a little girl with new shoes: always ready to dress up, to play, and to carry out the most difficult –or most unpredictable- task. So it’s no surprise that Björk has declared herself an avid Moomins fan. The family of animated beings invented by illustrator Tove Jansson in the mid 40’s has delighted generations of Finnish children, and are now playing the starring roles in a new 3-D film called “ Moomins And The Comet Chase ”. Björk didn’t let the opportunity to contribute a new song to the soundtrack pass by, and “The Comet Song”, made in collaboration with Sjon, is available from today on iTunes. The money from the sales of the track will go to UNICEF.
