High Quality Content by WIKIPEDIA articles! A nightclub (or night club or club) is a drinking, dancing and entertainment venue which does its primary business after dark. A nightclub is usually distinguished from bars, pubs or taverns by the inclusion of a dance floor and a DJ booth, where a DJ plays recorded dance and pop music. The music in nightclubs is either live bands or, more commonly, a mix of songs played by a DJ through a powerful PA system. Most clubs or club nights cater to certain music genres, such as techno, house music, heavy metal, garage, hip hop, salsa, dancehall, or soca music.
