The new Ici La Lune agency website takes us to outer space. The "lunar" music was composed in keeping with the agency's image. It is an invitation to weightlessness. NASA kindly agreed to let us use their astronauts' voices mixed with lunar sound effects. Musa Machina and Ici La Lune designed a sound management system called "dynamic music" : the music develops in layers according to the position of your mouse on the screen.
