Fleetwood Mac are a British rock band formed in 1967 which have experienced a high turnover of personnel and varied levels of success. From the band's inception through to the end of 1974, no incarnation of Fleetwood Mac lasted as long as two years.
The only member present in the band from the very beginning is its namesake drummer Mick Fleetwood. Despite band founder Peter Green naming the group combining his two former bandmates' surnames (from John Mayall's Bluesbreakers - it was actually the title Green had given to a demo recording they had recorded while in Mayall's band), bassist John McVie did not play on their first single nor at their first concerts. Keyboardist Christine McVie has, to date, appeared on all but two albums, either as a member or as a session musician. She also supplied the artwork for the album Kiln House.
The two most successful periods for the band were during the late 1960s British blues boom, when they were led by guitarist Peter Green, and from 1975 to 1987, with more pop-orientation, featuring Christine McVie, Lindsey Buckingham and Stevie Nicks. The band enjoyed more modest success in the intervening period between 1971 and 1974, with the line-up including Bob Welch, and also during the 1990s which saw more personnel changes before the return of Nicks and Buckingham in 1997, and more recently, the departure of Christine McVie. - Wikipedia
