#9: Fleetwood Mac — “The Chain” (1977)
Assembled from fragments of several discarded band demos, this track culminates in John McVie’s legendary isolated bassline that completely changes the song’s tempo and genre. The band stitched contrasting acoustic verses and electric refrains together, using a sudden pause to launch into a hard-rocking, guitar-solo finale. That dramatic shift transformed internal band tension into a unified masterpiece.
