Bernie Krause is a musician, author, soundscape recordist and bio-acoustician, and the author of The Great Animal Orchestra: Finding the Origins of Music in the World's Wild Places and other books. He also directs Wild Sanctuary.
Bernie made this recording in Aceh Province, Sumatra, Indonesia, in early March of 1991. In late 2004, a tsunami demolished much of the shoreline along the coast, and the surviving inhabitants needed wood for cooking and rebuilding. The nearby forest where this was recorded was their most accessible source. Much of that forest has been decimated and what is represented in this recording is a site that no longer resonates with anything like the rich biophonic textures that existed only a short time ago.
