Representing the anarchic and hedonistic side of the psychedelic subculture of the 60s and 70s, only the punkish British artist Ralph Steadman could equal the deranged writing of Hunter Thompson.

In the 1960s and '70s, countercultural artists opened their minds with psychedelics, entering planes of existence they sought to represent yet struggled to instantiate with conventional brushwork.

We don’t think of the psychedelic artists of the 1960s the same way we do the abstract expressionists of the 1940s or the Impressionists who came a century before.
