The emergent field of Soundscape Ecology reveals what nature sounds tell us about today’s changing eco-system – and the creatures that dwell in them. Since 1968, Wild Sanctuary has traveled the globe to record, archive, research, and express the voice of the natural world – its soundscape. These increasingly rare sounds of the wild inform and enrich our specialized efforts from the field to public performance. "Bernie Krause and his niche theory are the real thing. His originality, research and above all basic knowledge of the sound environments in nature are impressive."-- E. O. WILSON. 7:30pm. Free.
