To some commentators, the festival represented a sea change in musical preferences among young Bay Area radio listeners as the hippie culture fully arose in mid-1967. Alec Palao and Jud Cost chronicled the San Francisco mid-sixties era music scene in 1991 in their magazine "Cream Puff War #1". Writing about the weeks surrounding the Fantasy Fair, Cost noted that "the dichotomy in Bay Area music was never so evident, as the self-proclaimed "adult" scene separated itself from the "teen/pop" scenes." Scram Magazine juxtaposed that view with pioneer rock magazine editor Greg Shaw's recollection that the rift between the tastes of teens and adults didn't form until later, after the freeform radio style then being established by Tom Donahue fully emerged in the fall of 1967. A review of the bands that played indicates that most were groups that played the Fillmore and Avalon ballrooms and were part of the psychedelic rock scene at the time.
