Front Variations (One & Two)

Music for the retreating ice-sheets of Iceland, produced whilst on a 'Frontiers in Retreat' residency in Seyðisfjörður in 2016. www.frontiersinretreat.org/artists/richard_skelton Front Variations is composed from sine waves subjected to increasing amounts of feedback in order to simulate the so-called 'ice-albedo' feedback mechanism. This is the process whereby the action of melting glaciers reduces the global surface area of ice, thereby reducing the amount of solar radiation that glaciers reflect, which in turn increases global temperatures and causes further glacial melting. Ring modulation and distortion were also used to further deteriorate the sound signal. Front Variations is also available as part of Quoin 4 - the annual publication for friends and patrons of Corbel Stone Press. Quoin 4 features data collected by the World Glacier Monitoring Service and aerial photography of arctic glaciers from the US Naval Oceanographic Office. www.corbelstonepress.com/quoin-4
