"What have we become since 7 January 2015?" asks Nadia Vadori-Gauthier, one of the dancers and choreographer of the tribute show to the victims of the Charlie Hebdo attacks. This dancer has been campaigning for 10 years, dancing in the street for 1 minute a day. For nearly a year, she has been working on this anniversary project, which will take place this Tuesday 7 January at the Théâtre Chaillot in Paris. IMAGES AND SOUNDBITES
