11-Minute Psychedelic Rock Song Defied Radio Odds in 1966

An unusually lengthy psychedelic rock track from 1966 managed to break through as a radio hit despite running 11 minutes long - a rarity in an era when airplay favored shorter, punchier songs. The song's success challenged conventional wisdom about radio formatting and demonstrated audiences' appetite for experimental music during the height of the psychedelic era. The track became a notable example of how artistic ambition could still find mainstream success in the mid-1960s music landscape.
