This album is music produced for the soundtrack of Eric Michel's documentary film Les Blessures Invisibles (Invisible Wounds), which looks at the Gabonese town of Mounana, previously the site of a uranium mine which was the biggest supplier to the French nuclear industry, and the effect on the town of the mine closing down in 1999.

The album includes all the music which features in the film as well as material that was composed for it but ended up on the digital cutting-room floor.
