From a young age, Steve McGreevy was fascinated by the natural world and by amateur radio. When he discovered that nature produced its own radio signals, he began a quest to capture these sounds – a quest that has taken him to the most remote parts of the continent. Sometimes called the ‘Music of the Planet,’ this otherworldly soundscape surrounds us all the time but few ever get to listen to it. This film explores Steve’s motivations and takes the viewer on a sonic journey into this hidden world.
