The Xerces blue (Glaucopsyche xerces) is an extinct species of butterfly in the gossamer-winged butterfly family. The species lived in coastal sand dunes of the Sunset District of San Francisco peninsula. The Xerces blue is believed to be the first American butterfly species to become extinct as a result of loss of habitat caused by urban development. The last Xerces blue was seen in 1941 or 1943.
Silent Spring is the title of Rachel Carson’s book published in 1962 warning of the impending environmental disaster of unbridled industrial pesticide manufacture and use. This sound piece refers both directly and indirectly to Carson, related or inspired work such as Massive Attack’s track Silent Spring, Steven Stucky’s symphonic poem of the same title, as well as crop spraying and extracts from David Mitchell’s The Bone Clocks and Maggie Gee’s The Ice People. The work is a lament and dreaming of reversal knowing what otherwise lies ahead.
