Into the deep: Thomas Rex Beverly records the songs of humpback whales

Wedemark, August 2026 — Nature sound recordist Thomas Rex Beverly has spent years chasing the sounds of the natural world, from Patagonian mountain ranges to glaciers of Greenland to the ancient redwood canopies of California.

Armed with a trusted set of Sennheiser HD 300 PROtect headphones, his long-standing companions MKH 8020 microphones, and a bespoke 3D hydrophone array, Beverly undertook two expeditions, first to Hawaii and then to French Polynesia, in pursuit of high-definition, spatialised recordings that no researcher had previously been able to make.

From glaciers to the ocean floor

He found that while the existing recordings were interesting, he felt he could do more to really capture their other-worldly songs and the essence of their habitat, specifically with a more accurate recording of the vast spatial nature of the underwater world. His adventure began in Hawaii, where he recorded the unique underwater world of the wildlife around the Big Island, and ended in French Polynesia where, with the help of Sennheiser, he listened to the enticing songs of humpback whales...

BEHIND THE SCENES: 

The Ruthless Edit

Curation is a major part of being a field recordist. Rick Rubin calls this the ruthless edit. People often ask me what I think about when cutting. My response: "absolutely nothing". After ten years of editing nature soundscapes, my intuition is strong. If it’s a "hell yeah" I keep it. Nothing else survives.
