To many artists in the sixties who referred to the counterculture, or who used hallucinogenic drugs as an artistic tool, the term ‘psychedelic’ was seen as compromised and the idea of a ‘psychedelic art’ resisted. It is for this reason that ‘psychedelic art’ cannot be easily categorised as a genre; neither can it be understood as an entirely overlooked art form.
