Hanyo van Oosterom started the ambient collective CHI in 1983. Jacobus Derwort, a musician friend with Hanyo was the first musician to join CHI. Together, they went to the magic rock “The Kallikatsou” on the island of Patmos, Greece.

Here, Hanyo had stayed for months in a cave for some deep soul-searching. He heard CHI in the silence of the night like a message from out of space. Being together at the Kallikatsou they shaped the foundation of CHI, making handmade flutes from local bamboo and conducting field recordings of water, crickets, owls, goats, wind, etc.

After several years of collaborations with musicians like Willem Cramer and Michel Banabila, they decided to start together the beautiful The Chi Factory with which released (with the help of Ario Farahani and his label Astral Industries) some of the most beautiful records in the history of ambient music

Following the passing of group member J. Derwort in 2019, Hanyo van Oosterom’s legacy work brings about the next evolution of the Chi project: Son of Chi.

The sound of Hanyo Oosterom unfurls lushly overgrown 4th world drones, voices, and field recordings, naturally drifting between time-slowing beats, FM radio interference, and languid instrumentation combining the western retro-futuristic point of view, the New Age, and the ancestral eastern tradition.

In 2007 Hanyo invited the legendary Jon Hassell for two magical nights of “instant composing sessions” with the Numoonlab Orchestra in LantarenVenster in Rotterdam, Netherlands, with other special guests like Tony Allen (Fela Kuti), Ursula Rucker, Kain the Poet (Last Poets), Dwight Trible (Art Ensemble of Chicago), Omar Ka, Anthony Joseph, Colonel Red, Joe Bowie (Defunkt) and many more. The recordings are still online.

Arthur Flink was part of this Numoonlab Orchestra. Arthur is a trumpeter and electronic jazz producer from Rotterdam, Netherlands. Previously active in bands like Monsieur Dubois, State of Monc, and their collaboration project Monsieur Dodo, he now releases work through the FLiNK project.

In late 2022 Hanyo van Oosterom (Son of Chi) and Arthur Flink released ‘The Fifth World Recordings’. A tribute to the late Jon Hassell, who passed away in 2021, the album connects a deep running thread that captures perfectly the mysterious and magical world of the American trumpet player and composer.

"The World is Sound, Nature is Sound " - Nada Brahma

Tropical Ambient | New Age | Balearic | Exotica

„Looking back on the previous parts of the tropical mysteries, one quickly notices that the jungle journeys have become longer and longer. Ambient has always been a pleasant companion in my life. The yearning and the desire for deep relaxation has grown in recent years and especially in recent months and therefore probably the urge to immerse deeper and deeper into the rain forest with its secrets, and delay the return.“
