The Knife are working on an opera with Danish group Hotel Pro Forma called "Tomorrow in a year" based on the works of Charles Darwin. The Knife will be responsible for the music and libretto while the actual work will be performed by a femlae mezzo-soprano, a female actress and a male pop artist. Japanese artist Hiroaki Umeda will choreograph the dancers and art directer Maja Ravn and lighting designer Jesper Kongshaug will work on the visuals. Apparently The Knife's Olof Dreijer is currently in the Amazon creating field recordings of exotic animals to incorporate into the work.
Expect a September 2009 premiere. See pics from the prep workshop last September here: http://rabidrecords.com/tiay.html
