Laurent Pernice and Laurent Perrier bear very similar names. But the closeness between the two artists goes beyond mere coincidence. Both are ex-members of Nox, the mythical rock industrial French band of the 1980's. Since then, they have built a true personal and artistic complicity. In 1997, Laurent Pernice quits Paris to live in Marseilles, South of France, where Laurent Perrier visits him regularly. In 2005, on occasion of one of his visits, Perrier is invited to listen to Pernice's new works, a subtle encounter between piano pieces and ambient alectronic music. Much impressed by the quality of these works, Perrier decides to secreltly compose titles in the same style. Four years later, Perrier reveals his own works to Pernice and tells him his intention to publish them together with the (surprinsingly) still unpublished Pernice's titles.
