Sound as Time and Travel

This is our second and final long-play special. Our first Long Play focused on the Dawn Chorus, tracking how soundscapes evolve over time and give a deeper sense of place based on what they contain. In this special, we'll be tracking time on a global scale, starting with night and going through the day as we travel between the Africa, North America, and Australia. We'll also be taking a broader look at the types of vocalizations present in the world, including those from larger mammals like elephants and seals as well as geophonic sounds like those from bodies of water and the trees themselves. From time to time we'll be taking breaks to have some in-studio conversations between Jon Wohlfert, KBOO's Sound Artist Residency's Engineering Consultant and myself about whatever comes up on the mixing desk. 

We'll be starting the evening with a selection from “Night at the Elephant Bai” recorded by Bill McQuay in the Central African Repbulic while on assignment for the NPR series Radio Expeditions in 2002. The bai is a large clearing surrounded by forest. This will be flowed by some particularly mournful trees that I recorded last summer in the Sierra Nevadas around 6:00 AM. We'll follow that up with another sonic dawn at Koreelah Creek Camp in Koreelah National Park Queensland, Australia by ornithologist Mike Fitzgerald. We'll then hear the harbor seal nursery at Low Island in the San Juan National Wildlife Refuge recorded by Phil Green this past July. Finally, we will circle back to the Boundary Waters Canoe Area Wilderness in Minnesota recorded by Dr. Jacob Job at 2:30 PM in the afternoon.
