Leading proponents of the 1960s Psychedelic Art movement were San Francisco poster artists such as: Rick Griffin, Victor Moscoso, Bonnie MacLean, Stanley Mouse & Alton Kelley, and Wes Wilson. Their Psychedelic Rock concert posters were inspired by Art Nouveau, Victoriana, Dada, and Pop Art. Posters for concerts in the Fillmore West, a concert auditorium in San Francisco, popular with Hippie audiences, were among the most notable of the time. Richly saturated colors in glaring contrast, elaborately ornate lettering, strongly symmetrical composition, collage elements, rubber-like distortions, and bizarre iconography are all hallmarks of the San Francisco psychedelic poster art style. The style flourished from roughly the years 1966 to 1972. Their work was immediately influential to album cover art, and indeed all of the aforementioned artists also created album covers. 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 lightshow 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.
