Psychedelic light shows were a new art form developed for rock concerts. Using oil and dye in an emulsion that was set between large convex lenses upon overhead projectors, the light-show artists created bubbling liquid visuals that pulsed in rhythm to the music. This was mixed with slide shows and film loops to create an improvisational motion picture art form, and to give visual representation to the improvisational jams of the rock bands and create a completely "trippy" atmosphere for the audience.[citation needed] The Brotherhood of Light were responsible for many of the light shows in San Francisco psychedelic rock concerts.
