Topologies: from field recording to phonography and the virtual
The insights leading to the present project firstly manifested themselves in 2008, when I worked with field recordings on the basis of relatively well-established notions in music composition studies, such as ‘musical material’ and écriture. With hindsight, I understand the outcomes of those first experiments…
