A free party is a party "free" from the restrictions of the legal club scene. It typically involves a sound system playing electronic dance music from late at night until the time when the organisers decide to go home. A free party can be composed of just one system or of many. The parties can be thought of as autonomous zones where all the people present create and enforce the rules. The word free in this context is used both to describe the entry fee and the lack of restrictions and law enforcement. Motivations for organisers range from political protest to just wanting to have fun.
