Nat Evans’ The Lowest Arc presents documentation of a site-specific sound installation which took place on December 21, 2014. Handmade music boxes were programmed with scores generated by mapping constellations and were presented to visitors who were instructed to play the boxes while traversing the outdoor installation site. The pieces were echoed on six loudspeakers which circled the location, providing a wintry, glittering soundtrack to the urban landscape on the shortest day of the year, the Winter solstice. This collection is presented in digital format one year later as a celebration of the natural forces that dictate our bodies and our landscapes.
