What happens when musicians improvising on acoustic instruments sample and exchange their sound libraries? How can such a transgression of sonic territories contribute to an expanded understanding of one’s own sonic identity? And could this b/lending of identities point to a more ambiguous yet vibrant field of intra-play? Departing from these questions, this project intends to challenge our idea of sonic identity as a personal subject-oriented entity, and consequently investigate how a collaborative sharing of sampled sounds, can contribute to an expanded understanding of the sounds we play and are played by. Individual idiomatic approaches to one’s own instrument are thus interfered as we transgress habitual boundaries for action possibilities and musical imagination. The practice circulates from the duo of Torben Snekkestad and Søren Kjærgaard toward external collaborators, where the sharing process involves different approaches to audio sampling and mapping, embedding and embodying, listening and playing with each other’s sonic material to a point where authorship, origin, instrument and sonic identity is diffracted.
