ZAJ was a brave exponent of Spanish neodadaism with influences of zen and Marcel Duchamp vision of the arts.
The group received major contributions by different artists from the Spanish avant-garde scene, notably from the writer and diplomat José Luis Castillejo and from the interdisciplinary artist Esther Ferrer.
In 2011, Lex Records artist Boom Bip featured Le Bon's voice on the track "Do as I Do" on the Zig Zaj release.
