Sound Totem - Chain-Symmetry n^1

This Sound Totem contains the gestures of three different sedimentated piano improvisations. What is a sedimentated improvisation (or composition)? It is the sum of more than one improvisation (normally several) with an object (not necessarily a musical instrument) in which the next improvisation is performed without hearing the previous one. This makes the composition unique and impossible to perform another time, because it represents the sum of several gestures that occur only once and then never again.
