A trio of daredevil musicians known as Led Zipline takes to the skies for jamming sessions, dangling 300 meters above a French gorge. Mich Kemeter and his mates set up a hammock on a highline above the River Verdon - friend Armin Holzer then serenades Mich with a didgeridoo. Niccolo Zarattini, right, plays guitar and sings to Mich, left, and his girlfriend Karine while hanging from the rope with just one safety line. The incredible pictures were captured by thrill-seeking grapher Alexandre Buisse who watched in awe as the group strolled casually across the highline to rig the hammock - and chose to relax with an surprise gig.
