Pianisme is a collection of unreleased and out-of-print piano works composed and recorded since 2004. Most of them are part of soundtracks for feature films by French director Sébastien Betbeder (from 2007's Nuage and the very rare short film Nu devant un fantôme - whose music was completely unpublished until now). Also released for the first time: In the twilight of Paris (written the day after Luc Ferrari's death, as a quiet homage to a composer whose works have often been part of the Sub Rosa catalogue) and Soñando, straight repetition and variations on a minimal pattern, created for choreographer Christian Rizzo's 2010 show L'Oubli, toucher du bois.
