The work to create the installation took place both on-site at Samphire Hoe and within a radius of twenty miles of the site. The singular atmosphere and surroundings of Samphire Hoe was the starting point of the creative process, and the artists made use of the natural elements influencing the Tower to inform the installation. The intention is that the triggering of the sound installation will be affected by the activities of visitors to the Tower, and will also relate to changing conditions around the site.
At the centre of the Tower is a custom-built brass telescope that allows visitors to look out to sea. The base and bearing of this device have been fitted with magnetic reed switches that relate to the eight cardinal points/compass bearings. As the telescope is moved, a switch is activated to allow the control of data, depending on the orientation of the device. This movement activates the sound installation as well as allowing the controlled selection of audio files from digital storage devices.
Using 8 cardinal points of the compass, movement of the telescope triggers sound tracks that directly related to the landcspe that can be viewed through the eyepiece. Each location has been recorded using a high end stereo microphone onto a digital hard disk recorder. These direct sound scape recordings form the basis for the composition created by Geir Jenssen.
The sound installation developed organically through the collaboration between Geir Jenssen and Jony Easterby, with technical support from the engineer Graham Calvert of the company Sound Tech.
The artists have been collaborating on performances and sound installations in Norway and Europe since 1999, including an Arts Council of England Contemporary Music Network tour of the UK. Together they form part of the 'Natural Geographic' project focusing on improvisation and trans-national sound sources and ecology with the artist Ansuman Biswas. Previous sound installations in Norway, Germany and the UK have related to real-time sound manipulation through elemental forces such as geo-polar magnetism, Northern Lights activity, wind and water.
