Eccentric pop star Bjork has pulled out of plans to perform at the premiere of her new concert film at the London Film Festival on Thursday night (09Oct14).

The It's Oh So Quiet hitmaker had been expected to attend the screening of Biophilia Live at the Odeon West End and treat fans and guests to a short set, but she has decided to skip the event in favour of working on new music.

A statement posted on Bjork's Facebook.com page reads: "We are so sorry, but since Bjork is already working on her next album (out in 2015!) she cannot come to the 'Biophilia Live' premiere at the London Film Festival this week. Many sorries, and be well (sic)."

The film, directed by Peter Strickland and Nick Fenton, was shot at London's Alexandra Palace in September, 2013, on the final night of the singer's U.K. tour, which featured a series of multi-media designs and installations inspired by award-winning naturalist Sir David Attenborough.
