The piece was commissioned by Tromp International Percussion Competition Prize Winner Garrett Mendelow.
An ecotone is a transition area between distinct ecosystems, for example a marshland that sits between land and aquatic ecosystems. Such ecological tensions may gradually blend between ecosystems or they may sharply abut. This composition explores sonic ecotones by playing with the acoustic likeness of distinct bioregions and coupling recorded soundscapes with ecoacoustic percussion music. Under the ocean, the coral reef sounds a lot like a melting glacier. And the melting glacier sounds like flowing lava. The flowing lava itself has sonic qualities of the wind. And the gusts of wind share acoustic characteristics with the cicadas.

Each section is articulated by a distinct soundscape and by a unique ecoacoustic instrument combination.

These soundscapes were recorded by Matthew Burtner and EcoSono Institute in Guatemala, the West Indies, Alaska, and the US East Coast.
