On the top of the mountain, the wind is howling in the old installation of the ski station of Chacaltaya, Bolivia. The station was the highest in the world, and stops a few years ago, because of the smelting of the ice (du to global warming). 
The teleski cable and tube is still there and the wind sing in it! :-)

Félix Blume is a sound artist and sound engineer. 
His work is focused on listening, it invites us to live sonic experiences that enable a different perception of the surrounding. He uses sound as a basic material in sound pieces, videos, actions and installations. His process is often collaborative, working with communities, using public space as the context within which he explores and presents his works. He is interested in myths and their contemporary interpretation, in human dialogues both with inhabited natural and urban contexts, in what voices can tell beyond words.
