After "Lecteurs" in 2009 and "Happy Protest" in 2015, David Rolland, a choreographer from Nantes (west of France) proposes a new project called "Au milieu d'un lac de perles" (“In the Middle of a Lake of Pearls”). It takes place during "Les Tombées de la Nuit", a festival created in Rennes (Brittany, west of France) in the 1980s. This cultural and artistic event has been looking for alternatives to occupy the public space and to conceive the relation to the viewer.
