Nathan Davis’s Earthworks is a unique acousmatic piece, a 40-minute conceptual and musical love child of land art, environmental activism and music concrete in which the composer orchestrates the sonic outcome of the extraction, processing and use of common commercial materials of our contemporary built environment. It is an audio tapestry of drilling, fracking, stirring, slurring, scraping, cracking, popping and hammering, with the bright thread of one very intimate human voice woven through it.
