"Colouring of Pigeons," the first track from the official recording of the Knife's Charles Darwin-inspired opera Tomorrow, In a Year, is now available. Commissioned by Danish performance group Hotel Pro Forma and written in collaboration with Mt. Sims and Planningtorock, the Swedish duo's production was first performed this September in Copenhagen. Future performances are scheduled for Athens, Stockholm, and Munster, but if you can't make it to those, the album will be released digitally on February 2nd, with CDs hitting stores on March 9th.
