sublimation is a new music concert based on the poetic world of the clouds. Clouds are in a constant deformation and it is the will of the observer to see what he wants in them. Another image associated with clouds our their dialectic nature, heavy, dark clouds in contradiction with light, almost transparent one at the end of the sublimation. This world can be transposed in music and this is what between feathers are doing in this project. The listener can see what he wants in the ephemeral music played by the four musicians.
