Fleetwood Mac released nine studio albums during the 1970s. The run began with Kiln House in 1970 and ended with Tusk in 1979, covering several major changes in the band's lineup and musical direction.
The nine albums were Kiln House, Future Games, Bare Trees, Penguin, Mystery to Me, Heroes Are Hard to Find, Fleetwood Mac, Rumours, and Tusk. The first six belong largely to the band's transitional early-1970s period, when Danny Kirwan, Christine McVie, Bob Welch, and others shaped its sound after Peter Green's departure.
The count becomes especially important because Fleetwood Mac's albums from this decade are often grouped differently. Fleetwood Mac in Chicago was released in 1969, so it does not count. Compilation albums, live releases, and reissues also do not count as new studio albums.
The final three albums of the decade marked the band's transformation into a global pop-rock powerhouse. Fleetwood Mac introduced Stevie Nicks and Lindsey Buckingham to the lineup, Rumours became a landmark bestseller, and Tusk followed with a more experimental, sprawling approach.
