The Psychedelic era was the time of social, musical and artistic change influenced by psychedelic drugs, occurring from the mid-1960s to mid-1970s. The era was defined by the proliferation of LSD and its following influence in the development of psychedelic music and psychedelic film in the Western world. Writers who explored the potentials of consciousness exploration in the psychedelic era included Alan Watts, Timothy Leary, Ralph Metzner, and Ram Dass among others; an important journal of the time was The Psychedelic Review. History Origins Throughout the 1950s, mainstream media reported on research into LSD and its growing use in psychiatry, and undergraduate psychology students taking LSD as part of their education described the effects of the drug. Time magazine published six positive reports on LSD between 1954 and 1959. From the second half of the 1950s, Beat Generation writers like William Burroughs, Jack Kerouac and Allen Ginsberg wrote about and took drugs, including cannabis and Benzedrine, raising awareness and helping to popularise their use.

From 1964 the Merry Pranksters, a loose group that developed around novelist Ken Kesey, sponsored the Acid Tests, a series of events involving the taking of LSD (supplied by Stanley), accompanied by light shows, film projection and discordant, improvised music by the Grateful Dead (financed by Stanley), then known as the Warlocks, known as the psychedelic symphony. The Pranksters helped popularise LSD use, through their road trips across America in a psychedelically decorated converted school bus, which involved distributing the drug and meeting with major figures of the beat movement, and through publications about their activities such as Tom Wolfe's The Electric Kool-Aid Acid Test (1968). San Francisco had an emerging music scene of folk clubs, coffee houses and independent radio stations that catered to the population of students at nearby Berkeley and the free thinkers that had gravitated to the city. There was already a culture of drug use among jazz and blues musicians, and in the early 1960s use of
