A rave (from the verb: to rave) is an organized dance party at a nightclub, an outdoor festival, warehouse, or other private property or public spaces, typically featuring performances by DJs, playing a seamless flow of electronic dance music. The word also means excellent, great, or brilliant, and can be used to describe any genre of music and entertainment. At its broadest definition, "rave" can be used to describe many forms of music, not limited to just rave music- which is why fusion genres exist, even within rave music itself. DJs at rave events play electronic dance music on vinyl, CDs and digital audio from a wide range of genres, including techno, hardcore, house, bassline, dubstep, New Beat and post-industrial. Occasionally live musicians have been known to perform at raves, 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.
