Some amazing students from Lausanne University built the structure below on a mountain top at an altitude of 2055m! It was part of the Eco Village Conference in Les Diablerets.
Believe it or not this was my stage.

On one of the sides of the structure some strings had been added to create a, sort of, harp.
Cows were also allowed entry to the recital. I think they added to it somewhat with their bells and "moos".
The programme consisted of French song, Schubert and some local Swiss folk songs put together with Anne-Marie, classical guitar.
NB. The downside of singing on a mountain top was having to sing the first verse of Ave Marie with a fly in my mouth.
