A percussion quartet by composer and artist Nathan Hall, 2011. Filmed in Boulder, Colorado, a collaboration with Jeff Weber of the National Center for Atmospheric Research. The percussionists in each quadrant all play musical interpretations of wind data that are unique to Boulder Colorado’s ‘Chinook’ winds. As the winds pick up speed, so does their playing, and as atmospheric pressure drops, the sound of their instruments gets lower. There is a moment of rest in the piece where birds make an appearance as well.
