Sound artists Richard Chartier and Taylor Deupree created ‘Specification.Fifteen’ as a commission for the Hirshhorn Museum and Sculpture Garden in Washington DC on the occasion of a retrospective exhibition of renowned Japanese photographer Hiroshi Sugimoto. His series of seascapes inspired Chartier's and Deupree's live piece which premiered in March 2006 in front of the panoramic window of the museum as the sun set across the city's skyline. ‘Specification.Fifteen’ evokes and contrasts the still spaces of Sugimoto’s seascapes which suggest continuous change under a seemingly uniform surface.
