We like to think we've constantly got our fingers on the musical pulse, but sometimes we need a helping hand. On this particular occasion our guiding light was none other than Bjork. Always one to pick the best collaborators, Bjork announced a few months back that she would perform at a charity gig with New York's Dirty Projectors.

Who are this motley crew we asked ourselves? Well, they're fronted by a man called Dave Longstreth and there are five other people in the band (although not in the photo), some of whom are women and some of whom are men. Fascinating so far. They also make music that is difficult to categorise, relies heavily on vocals and can sometimes sound on the brink of collapse but beautiful at the same time. Sound familiar?

They have a new album coming out next week entitled Bitte Orca and from said album, this is 'Stillness Is The Move':

Below is some slightly dodgy footage of Bjork performing with Dirty Projectors on a song Longstreth composed especially for the one-off gig. Fast forward through all the talking and tuning up and get to the part with those amazing backing vocals and Bjork's passionate rasp, blurting out lyrics about whales and love.
