Liquid light shows are a form of light art that surfaced in the early 1960s as accompaniment to electronic music and avant-garde theatre performances. They were later adapted for performances of rock or psychedelic music.

Live event support includes staging, scenery, mechanicals, sound, lighting, video, special effects, transport, packaging, communications, costume and makeup for live performance events including theater, music, dance, and opera. They all share the same goal: to convince live audience members that there is no better place that they could be at the moment. This is achieved through establishing a bond between performer and audience. Live performance events tend to use visual scenery, lighting, costume amplification and a shorter history of visual projection and sound amplification reinforcement.
