Concert halls

A nightclub or dance club is a club that is open at night, usually for drinking, dancing and other entertainment. Nightclubs often have a bar and discotheque (usually simply known as disco) with a dance floor, laser lighting displays, and a stage for live music or a disc jockey (DJ) who mixes recorded music. Nightclubs tend to be smaller than live music venues like theatres and stadiums, with few or no seats for customers.
