Book: SECRET SOUNDS OF PONDS
About the Book
In Secret Sounds of Ponds, environmental musician and philosopher David Rothenberg tosses a microphone into a pond and we read (and hear) about an entirely new realm: the unexpected and stirring rhythms of some of the smallest and loudest creatures on Earth. Recording the songs of the animals and plants inhabiting each pond reveals a different perspective than what we meet in our human society. Rothenberg makes this music real though his engaging prose and conversations with environmentalists ranging from Werner Herzog to Peter Gabriel to ecologists specializing in these unique waterscapes. Each pond episode brings the reader closer to a new understanding of the non-human world that we share.
