With particular focus on improvisation since 1997, David explores the relation with other artistic practices such as dance (with Fine Kwiatkowski, Valérie Métivier, Véronique Albert, Yukiko Nakamura), poetry (with Ly Thanh Tiên) or experimental films ( with Xavier Quérel, Christophe Auger, Etienne Caire, Gaêlle Rouard)... 

Due to his interest in reality as the subject-matter for play, he met a group of artists by the name of Ouie/Dire (Marc Pichelin, Jean Pallandre, Laurent Sassi, Xavier Charles, Isabelle Duthoit, Kristoff Guez) with whom he developed links between "musical" improvisation and phonography. 

As an improviser, he has participated in numerous meetings and developed several long-term collaboration with musicians such as Jean Luc Guionnet, Frédéric Blondy, Michel Doneda, Isabelle Duthoit... He has played in Europe, the United States, Lebanon, Africa, Estonia, Japan... He is a co-founding member of Le Clou, a Dordogne-based association which seeks to review and disseminate improvisation practices.
