A live band dance is an event where the means of serving the dancefloor involves the use of a live band.
Before the rise of discothèques and DJ-based dancefloors with recorded music (prior to the 1950s); live bands were the ubiquitous means of serving the dancefloor. Along with that, slow-dancing was the primary method of dancing at the time. However; the rise of Rock and Roll music initially made it hard for people to dance when it was popularized in the early 1950s, however people quickly adapted to it and started dancing at higher speeds almost coinciding the rise of DJ-based dancefloors. Live bands have quickly been displaced by DJ-based dancefloors as the DJ stands took up less space than bandstands and that it played recorded music.
Live band dances are still used on occasion at ballrooms. Along with that, moshpits have live punk rock bands, so people are able to hear the hardcore sound associated with moshing. Some formal dances such as proms use live bands as a means of serving the dancefloor. Also, some people choose live bands because they believe there are virtually no space constraints for the band's instruments. Dance parties with high-end formality have also preferred live bands as means of serving the dancefloor.
