Rave

A rave (from the verb: to rave) is a large dance party featuring performances by DJs and occasionally live performers playing electronic music, particularly electronic dance music (EDM). The music is amplified with a large, powerful sound reinforcement system, typically with large subwoofers to produce a deep bass sound. The music is accompanied by laser light shows, projected images, visual effects and fog machines. The word "rave" was first used in the late 1980s to describe the subculture that grew out of the acid house movement.

While some raves may be small parties held at nightclubs or private residences, some raves have grown to immense size, such as the Castlemorton Common Festival in 1992. Some electronic dance music festivals have features of raves, but on a large, often commercial scale. Raves may last for a long time, with some events continuing for ten hours. Due to the association of illegal party drugs such as MDMA (ecstasy) and the use of non-authorized, secret venues for some raves, such as squat parties at warehouses, law enforcement attention has been directed at the rave scene in many countries.
