Durham made this video with Maria Thereza Alves. It begins as a nature documentary, accompanied by trumpet sounds. Just when the viewer begins to wonder what animals do make such a sound, the sounds of working people and birds reach his ear. This is followed by a visual cue: a procession of people is shown, all blowing bird whistles. The participants perform the strangest acts; the viewer can only guess at their motives. Only when the camera zooms out and shows what was previously left out of sight, we get a hint. The whistlers are making music, while interpreting the sounds from the forest in their own way.
