Šis „Unarcheology Radio“ grojaraštis pateikia įsivaizduojamą garsovaizdį, kuris sudarytas iš svirplių, cikadų ir laumžirgių garsų iš viso pasaulio, kartu su šikšnosparnių ultragarsu, čia perkeltu į girdimus dažnius. Montažo pagalba randasi nelogiška garsų ekosistema, kurios elementai paprastai yra labai toli vieni nuo kitų ir nuo mūsų tiek geografiniame žemėlapyje, tiek garso spektre.
