"On the 30th April 2017 world-famous climber Ueli Steck died on Mount Nuptse whilst acclimatizing for one of his biggest climbs yet – climbing both Mount Everest and Mount Lhotse without the use of bottled oxygen. A year later, Ueli’s close friends Jonathan Griffith and Sherpa Tenji attempted to finish off his project. Tenji would try the climb without bottled oxygen whilst internationally award-winning cameraman Jonathan Griffith captures the entire story with a 8K 3D VR Ambisonic camera."
