During 28 minutes, its 5 movements explore the importance of balance in the relationship between humans and their environment through a tour conducted in diverse ecosystems on a hi-res music-interactive live cinema film. On stage it is performed by the author with synthesizers and there is an option for full orchestra or local musicians ensemble.
