Born in 1972 in Châteauroux, David Legrand is a pioneer of collective and experimental art, operating between Biarritz and Bourges. His multidisciplinary practice blends video, virtual reality, and a pedagogy he refers to as "transpedagogical," creating hubs of cooperation between artists and students, where each artwork is transmuted into an evolving matrix. Co-founder of La Galerie du Cartable, a nomadic video collective founded in 1999, he advocates for radical pedestrian mobility and autonomy in audiovisual creation.

Legrand is also the founder of Hall Noir and its new base, an autonomous artistic cooperative developed within the Bandits-Mages association and later at Antre Peaux (2013-2021). This cooperative continues today in a nomadic version in the Nouvelle-Aquitaine region, enabling students and artists to co-create, fostering alternative distribution networks, and promoting non-commercial and non-competitive ideas of art, which he refers to as the "system-ARTISTE."

This "system-ARTIST" supports a collective dynamic through large-scale video spaces, designed as self-built shooting stages or alternative metaverses. Legrand explores transmuted works, layering virtual and physical spaces to regenerate them into unfixed poetic matter, while continuing the idea of shared and open creation.
