Psychedelic art is visual work inspired by the hallucinatory, consciousness-expanding experiences associated with drugs such as LSD, psilocybin and DMT. The term was coined by the British psychologist Humphry Osmond in the 1950s, but the art movement proper belongs to the late-1960s and early-1970s counterculture, above all in San Francisco, where concert posters for the Fillmore and Avalon ballrooms turned lettering into melting, pulsating color. It was the visual counterpart of psychedelic rock: distorted, surreal imagery, full-spectrum color and swirling optical patterns meant to evoke or enhance the trip. Beyond posters it took in album covers, liquid light shows, murals, underground comics and newspapers, often carrying the counterculture's political and spiritual charge, and it has been periodically revived ever since.
