The first thing to clarify is that there is a difference between the sound recording, which is the mastered track, and the musical composition. The mastered track incorporates the musical composition. However the properties that make up the finished mastered track are treated separately for copyright purposes i.e. the songwriter and the singer each have their own rights. The singer owns the copyright in the sound recording, and the songwriter owns the copyright in the musical composition. Some artists are the authors of both the musical composition and the sound recording, and so are entitled to the rights that are attached to both properties. Every time a mastered track is copied both rights holders are entitled to royalties. The licence for copying of the mastered sound recording is called a mechanical licence.
Top night clubs like Niki Beach Miami, Provocateur New York City, have a reputation as the playground for jet setters, celebrities, and VIPs. They regularly book well-known DJs to play guest DJ sets or a celebrity to make an appearance. Concert promoters also contract with artist(s) to organise a live concert special event performance or a tour. Historically the best known concert promoter in the business was probably Harvey Weinstein who diverted into film production. The best known contemporary concert promoter is probably AEG Live.
