A rave (from the verb: to rave) is an organised dance party at a nightclub, outdoor festival, warehouse, or other private property typically featuring performances by DJs, playing a seamless flow of electronic dance music. DJs at rave events play electronic dance music on vinyl, CDs and digital audio from a wide range of genres, including techno, hardcore, house, drum & bass, dubstep, and post-industrial. Occasionally live performers have been known to perform, in addition to other types of performance artists such as go-go dancers and fire dancers. The music is amplified with a large, powerful sound reinforcement system, typically with large subwoofers to produce a deep bass sound. The music is often accompanied by laser light shows, projected coloured images, visual effects and fog machines.
