Finnish performance-artist Tero Nauha, Mark and John Bain - an artist and an architect from Seattle - have done collaborative sound-performances. Aside from that John Bain has his sound-project, MDO (Mutant Data Orchestra), collaborating with various people. Mark Bain uses vibration and sound in his sculptures and installations. Tero Nauha is working with human voice in his performances.

Their collaborative performances are collaborations of human/body and electric sounds. The machines and the human body work both as the sources and receivers of sound impulses. Mark, John and Tero build a reciprocal system where the bodies of the audience take part, while the sound is a highly sensory experience.

In the performance Tero clearly has the more physical and dynamic role of the performer, while Mark and John take care of the machines. They feed the impulses to the performer through the machines that are attached to his body. At first it looks like the machine is superior to the body, until it becomes clear that the body also feeds impulses to the machine. It is a complex mesh between the puppeteer and the puppet.

The collaboration is a non-linear and dynamic process, whereas each performance has its own specific rules and each performance is an attempt to activate the space and time through sound and movement. This process is built from chaos-material, and therefore is not repeatable, but it can be altered by subtle changes. "Accumulator" generates energy for the dynamic of the process. Chaos is constantly present, the performance is about the choices one makes. In a performance it is not possible to use linear descision making models, because they won’t work in complex and dynamic, non-linear systems. Simple models work for machines, tools - the extensions of the hand - but at the same time the tools create material, and they are susceptible to disturbance and variation. The machines that are used in the performance are re-wired, this variation creates hybrids or mutants, which are not fully controllable, they don’t work according to linear systems. A choice between ‘A’ and ‘B’ does not guarantee that one reaches the goal. Self-organising, non-linear systems are not static but dynamic spaces, where the rules are also variable. Still, one must remember that the performance situation is limited, where performers decide the rules for the duration, material and space. In spite of that, the dynamic situation that has appeared is not a product, not a document.

The performance is not productive or visionary. It sets up guidelines for variation of experience or experiment.
