Cercle is one of the most respected live-streaming platforms in dance music, broadcasting performances in breathtaking locations to tens of millions of viewers across the globe. From hot air balloons to mountain tops, waterfalls, world-heritage sites, and under the Northern Lights in the arctic circle. Part videographers and music curators, part adrenaline junkies, Cercle blend sound with mind-blowing images and aesthetic, creating audio-visual experiences in which viewers are immersed from start to finish. Broadcaster and DJ Frank McWeeny follows founder Derek Barbolla and his team of creatives for nine months, as they plan and broadcast a show under a waterfall in a remote part of Bosnia and Herzegovina. What makes it a perfect location? How is the artist selected? And with multiple cameras, drones, and a live audience of one thousand, how difficult is it to capture? From the importance of colour to the best time of day to film, we uncover the technical and logistical challenges of pulling off a production of this magnitude.
