Free festivals are a combination of music, arts and cultural activities, for which often no admission is charged, but involvement is preferred. They are identifiable by being multi-day events connected by a camping community without centralised control. The pioneering free festival movement started in the UK in the 1970s.

The Arts Lab was an alternative arts centre, founded in 1967 by Jim Haynes at 182 Drury Lane, London. Although only active for two years, it was influential in inspiring many similar centres in the UK, continental Europe and Australia, including the expanded Institute of Contemporary Arts (ICA) in London, the Milky Way/Melkweg in Amsterdam, the Entrepôt in Paris and the Yellow House Artist Collective founded by Martin Sharp in Sydney.
