GRAND is a 22-foot sculptural portrait of the Grand River after midnight. The work is comprised of three acrylic blocks carved into a realistic cross-section of the Grand River. To create the surface, Collier has developed a software model of wind and current in the Grand Rapids area and incorporated patterns of sound waves from the region, allowing her to make a solid object from the intangible sound and water waves. The work itself, while using sound in its design, is silent, reflecting the stillness of deep night. To create GRAND, Collier incorporated sounds from various sources, including her own on-site recordings, oral histories, music, and sounds provided by the public.
