For this collaboration, sound artists Richard Chartier and Taylor Deupree were invited by the Hirshhorn Museum and Sculpture Garden, Washington, DC, to create a new live work inspired by the Seascapes series of renowned Japanese photographer Hiroshi Sugimoto on the occasion of his retrospective exhibition. The result is this live recording, Specification.Fifteen. This work premiered on March 30, 2006 in front of the curved panoramic window of the Museum's Lerner Room as the sun set across the city's skyline. Specification.Fifteen evokes the stillness and opposing yet related spaces of Sugimoto's Seascapes, which suggest infinitesimal change and variation under a seemingly uniform surface.
