“Rhiannon,” written by Stevie Nicks and released by Fleetwood Mac in 1975, became one of the band’s signature songs, peaking at #11 in the U.S. and later hailed by Rolling Stone among the greatest songs of all time. Often introduced by Nicks as “a song about an old Welsh witch,” its live performances between 1975–82 grew into fiery, theatrical moments that captivated audiences. Mick Fleetwood once described Nicks’s electrifying delivery as “like an exorcism.”
