As I understand it, the difference between a dance club and a rave is that raves are parties that spring up almost spontaneously in different locations.
Someone puts out the word on the Internet, via e-mail, and it spreads.
Others get a voice mail message and pass it along. Participants gather, illegally, at the designated place at the appointed time, pay an entrance fee, and the celebrated DJs take turns, working in shifts to provide the music. This film supposedly chronicles in pseudo-documentary tone one night at a rave. It begins on Friday with an e-mail, announcing tomorrow's event. Real-life DJs with names like Digweed and Dimitri vary the pace and mood by changing the tempo and tone of the music.
