The six works represented on these two CDs (ranging from 5 to 45 mins) exist as documentation of performed events that are not repeatable, in the same way that notated musical works generally are. However, while they involved improvisational elements, they are not to be regarded as "improv" since they were rigorously composed for the environmental circumstances in which they took place. They represent an attempt to articulate an aesthetic of environmental interactivity through sound-making, which occupied David Dunn over a 15-year period.

A diverse body of work which share the characteristic of having been outdoor performances. They also demonstrate a progressive expansion of context, moving from interactions with a single member of another species toward interactions with complex environments. Foremost in these experiments was a concern for sound as a means to explore the emergent intelligence of non-human living systems.

"The listener must tolerate a wide range of unusual acoustic spaces and an even greater range of technical quality. I recommend that listeners adjust their audio expectations to accommodate these eccentric demands through understanding that the non-studio production values were intentional and inseparable from the reality of the art".
