This is really just an excuse to make use of some lovely music I recorded in Kiribati a long time ago. It's been sitting in the filing cabinet for far too long, and that seemed like a shame.

In this episode, Mark Chella discusses Malaysia's Iban culture, and it's most controversial feature: headhunting.

Almost everyone who visits Hong Kong marvels at the massive bamboo scaffoldings that cling to the side of the city's towering skyline. In this episode, cultural preservationist Cardin Chan tells me about a close relative of this feature of Hong Kong life, bamboo theatres. They're huge temporary structures built for festivals. We also chat about efforts to preserve the city's disappearing neon signs.

Mark Graham and I march up a stream in the New England National Park in search of the tallest tree in New South Wales. The hike takes us through some of Australia's most pristine rainforest. But things take a hell of a turn.

This is part one of a two part adventure, in which we go searching for the biggest tree in New South Wales. It was under threat from Australia's massive bushfires. In this episode, we look at some of the damage, and try to meet some of the nightlife in the forest.

This is a story of resilience. It's about what you do when your house burns down in the biggest bushfires in living memory. Rod Hayes is an architect who built his dream home on a mountaintop. He lovingly picked out sustainable materials from all around the state to build it. But nothing could stop the raging inferno.

A few quick notes about the Humidity, which will be available from next week. Exciting episodes are on the way.
