An international avant-garde group or collective that was founded and flourished in the1960s but still continues today
The group was founded and named in 1960 by the Lithuanian/American artist George Maciunas; originally for an eponymous magazine featuring the work of a group of artists and composers centred around John Cage. The Latin name means flowing. In English a flux is a flowing out. Maciunas said that the purpose of Fluxus was to promote a revolutionary flood and tide in art, promote living art, anti-art. This has strong echoes of dada with which Fluxus had much in common.
The group came together on the continent, first in Germany where Maciunas worked for the US Army. Fluxus subsequently staged a series of festivals in Paris,Copenhagen, Amsterdam, London and New York at which activities included concerts of avant-garde music and performances often spilling out into the street.
Fluxus played an important part in the opening up of definitions of what art can be that led to the intense and fruitful pluralism seen in art since the 1960s (see e.g. conceptual art, performance art, film & video art, postmodernism).
Its heyday was the 1960s but it still continues.
