Nightclub or Music Club
A nightclub, music club or club, is an entertainment venue and bar that usually operates late into the night. A nightclub is generally distinguished from regular bars, pubs or taverns by the inclusion of a stage for live music, one or more dance floor areas and a DJ booth, where a DJ plays recorded music. The upmarket nature of nightclubs can be seen in the inclusion of VIP areas in some nightclubs, for celebrities and their guests. Nightclubs are much more likely than pubs or sports bars to use bouncers to screen prospective clubgoers for entry. Some nightclub bouncers do not admit people with informal clothing or gang apparel as part of a dress code. The busiest nights for a nightclub are Friday and Saturday night. Most clubs or club nights cater to certain music genres, such as house music or hip hop.
Disco is a music genre and subculture that emerged in the mid-1960s and early 1970s from the United States’ urban nightlife scene. In Germany a Disco is a Music Club.
