 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 drugs including cannabis, peyote, mescaline and LSD began to grow among folk and rock musicians.One of the first musical uses of the term "psychedelic" in the folk scene was by the New York-based folk group The Holy Modal Rounders on their version of Lead Belly's 'Hesitation Blues' in 1964.
