On Jazz: Vingt ans de l’orchestre national de jazz explores the visual narrative of two decades of France’s National Jazz Orchestra. Guy Le Querrec employs a documentary style that captures the intensity, spontaneity, and emotional depth found in live jazz performances.

The collection showcases dynamic compositions, intimate musician portraits, and onstage moments that reveal the creative energy and evolving spirit of the orchestra. The black-and-white photographs emphasize contrasts and textures that underline jazz’s rhythmic and improvisational qualities.

Published in 2007 by creaphis editions, this 152-page volume serves as both a historical record and an artistic tribute to jazz culture in France.
