The second single from Kari van der Kloot’s album “Window”, Trust Exercise depicts the feeling of trying to hold on to a single moment out of fear that it might not last. The introduction for this song features a hybrid flute/alto flute/bass flute and voice choir that was built layer by layer in the studio to create a fuzzy, mysterious, hard to grasp type of sound. The featured soloist is Elsa Nilsson on flute.
