Vinyl LP pressing. 2019 collection. In response to their 2004 debut album, which became an instant classic, Marc Collin and Olivier Libaux experimented with various musical paths. Many songs were thus recorded, and the songs that were relevant to each album's theme were released, but many covers remained under wraps, while others, although ready for release, were relegated to the vaults. These previously unreleased recordings are featured on Curiosities.
