While most bands undergo a number of changes over the course of their careers, few of them experienced a more radical stylistic evolution than Fleetwood Mac. Initially conceived as a hard-edged British blues combo in the late '60s, the band gradually evolved into an incredibly popular and influential pop/rock act over the course of a decade. Originally, guitarists Peter Green and Jeremy Spencer provided the group with their gutsy psychedelic blues-rock sound, then the band moved toward pop/rock with the addition of keyboardist/songwriter Christine McVie. By the mid-'70s, Fleetwood Mac relocated to California, where they added the duo of Lindsey Buckingham and Stevie Nicks to their lineup; the latter pair's writing and vocals helped the band become one of the most popular groups of the late '70s. Combining melodic soft rock with the confessional introspection of singer/songwriters, 1977's Rumours become one of the biggest-selling albums of all time. The band retained their popularity through the early '80s, when Buckingham, Nicks, and McVie all began pursuing solo careers. The group reunited for 1987's Tango in the Night, but after more lineup changes and instability, they split after 1995's Time. The band quickly reunited, though, assembling for The Dance, a 1997 live album, then stabilizing without Christine McVie for their 2000s incarnation, a lineup that produced 2003's Say You Will. McVie returned to the fold for a series of successful tours starting in 2014, but the group harmony was short-lived. Buckingham was ousted prior to an anniversary tour in 2018, his departure proof that the one constant in Fleetwood Mac through the years was change.

The roots of Fleetwood Mac lie in John Mayall's legendary British blues outfit, the Bluesbreakers. Bassist John McVie was one of the charter members of the Bluesbreakers, joining the group in 1963. In 1966 Peter Green replaced Eric Clapton, and a year later drummer Mick Fleetwood joined. Inspired by the success of Cream, the Yardbirds, and Jimi Hendrix, the trio decided to break away from Mayall in 1967. At their debut at the British Jazz and Blues Festival in August, Bob Brunning was playing bass in the group, since McVie was still under contract to Mayall. He joined the band a few weeks after their debut; by that time, slide guitarist Jeremy Spencer had joined the band. Fleetwood Mac soon signed with Blue Horizon, releasing their eponymous debut the following year. Fleetwood Mac was an enormous hit in the U.K., spending over a year in the Top Ten. Despite its British success, the album was virtually ignored in America. During 1968, the band added guitarist Danny Kirwan. The following year, they recorded Fleetwood Mac in Chicago with a variety of bluesmen, including Willie Dixon and Otis Spann. The set was released later that year, after the band had left Blue Horizon for a one-album deal with Immediate Records; in the U.S., they signed with Reprise/Warner Bros., and by 1970, Warner began releasing the band's British records as well.

Fleetwood Mac released English Rose and Then Play On during 1969, which both indicated that the band was expanding its music, moving away from its blues purist roots. That year, Peter Green's "Man of the World" and "Oh Well" were number two hits. Though his music was providing the backbone of the group, Green was growing increasingly disturbed due to his large ingestion of hallucinogenic drugs. After announcing that he was planning to give all of his earnings away, Green suddenly left the band in the spring of 1970; he released two solo albums over the course of the '70s, but he rarely performed after leaving Fleetwood Mac. The band replaced him with Christine Perfect, a vocalist/pianist who had earned a small but loyal following in the U.K. by singing with Spencer Davis and the Chicken Shack. She had already performed uncredited on Then Play On. Contractual difficulties prevented her from becoming a full-fledged member of Fleetwood Mac until 1971; by that time she had married John McVie.

Christine McVie didn't appear on 1970's Kiln House, the first album the band recorded without Peter Green. For that album, Jeremy Spencer dominated the band's musical direction, but he had also been undergoing mental problems due to heavy drug use. During the band's American tour in early 1971, Spencer disappeared; it was later discovered that he left the band to join the religious cult the Children of God. Fleetwood Mac had already been trying to determine the direction of their music, but Spencer's departure sent the band into disarray. Christine McVie and Danny Kirwan began to move the band toward mainstream rock on 1971's Future Games, but new guitarist Bob Welch exerted a heavy influence on 1972's Bare Trees. Kirwan was fired after Bare Trees and was replaced by guitarists Bob Weston and Dave Walker, who appeared on 1973's Penguin. Walker left after that album, and Weston departed after making its follow-up, Mystery to Me (1973). In 1974, the group's manager, Clifford Davis, formed a bogus Fleetwood Mac and had the band tour the U.S. The real Fleetwood Mac filed and won a lawsuit against the imposters who, after losing, began performing under the name Stretch -- but the lawsuit kept the band off the road for most of the year. In the interim, they released Heroes Are Hard to Find. Late in 1974, Fleetwood Mac moved to California, with hopes of restarting their career. Welch left the band shortly after the move to form Paris.

Early in 1975, Fleetwood and McVie were auditioning engineers for the band's new album when they heard Buckingham-Nicks, an album recorded by the soft rock duo Lindsey Buckingham and Stevie Nicks. The pair were asked to join the group and their addition revived the band's musical and commercial fortunes. Not only did Buckingham and Nicks write songs, but they brought distinctive talents the band had been lacking. Buckingham was a skilled pop craftsman, capable of arranging a commercial song while keeping it musically adventurous. Nicks had a husky voice and a sexy, hippie gypsy stage persona that gave the band a charismatic frontwoman. The new lineup of Fleetwood Mac released their eponymous debut in 1975 and it slowly became a huge hit, reaching number one in 1976 on the strength of the singles "Over My Head," "Rhiannon," and "Say You Love Me." The album would eventually sell over five million copies in the U.S. alone.

While Fleetwood Mac had finally attained their long-desired commercial success, the band was fraying behind the scenes. The McVies divorced in 1976, and Buckingham and Nicks' romance ended shortly afterward. The internal tensions formed the basis for the songs on their next album, Rumours. Released in the spring of 1977, Rumours became a blockbuster success, topping the American and British charts and generating the Top Ten singles "Go Your Own Way," "Dreams," "Don't Stop," and "You Make Loving Fun." It would eventually sell over 17 million copies in the U.S. alone, making it the second biggest-selling album of all time. Fleetwood Mac supported the album with an exhaustive, lucrative tour and then retired to the studio to record their follow-up to Rumours. A wildly experimental double album conceived largely by Buckingham, 1979's Tusk didn't duplicate the enormous success of Rumours, yet it did go multi-platinum and featured the Top Ten singles "Sara" and "Tusk." In 1980, they released the double album Live.

Following the Tusk tour, Fleetwood, Buckingham, and Nicks all recorded solo albums. Of the solo projects, Stevie Nicks' Bella Donna (1981) was the most successful, peaking at number one and featuring the hit singles "Stop Draggin' My Heart Around," "Leather and Lace," and "Edge of Seventeen." Buckingham's Law and Order (1981) was a moderate success, spawning the Top Ten "Trouble." Fleetwood, for his part, made a world music album called The Visitor. Fleetwood Mac reconvened in 1982 for Mirage. More conventional and accessible than Tusk, Mirage reached number one and featured the hit singles "Hold Me" and "Gypsy."

After Mirage, Buckingham, Nicks, and Christine McVie all worked on solo albums. The hiatus was due to a variety of reasons. Each member had his or her own manager, Nicks was becoming the group's breakaway star, Buckingham was obsessive in the studio, and each member was suffering from various substance addictions. Nicks was able to maintain her popularity, with The Wild Heart (1983) and Rock a Little (1985) both reaching the Top 15. Christine McVie also had a Top Ten hit with "Got a Hold on Me" in 1984. Buckingham received the strongest reviews of all, but his 1984 album Go Insane failed to generate a hit. Fleetwood Mac reunited to record a new album in 1985. Buckingham, who had grown increasingly frustrated with the musical limitations of the band, decided to make it his last Fleetwood Mac project. When the resulting album, Tango in the Night, was finally released in 1987, it was greeted with mixed reviews but strong sales, reaching the Top Ten and generating the Top 20 hits "Little Lies," "Seven Wonders," and "Everywhere."

Buckingham decided to leave Fleetwood Mac after completing Tango in the Night, and the group replaced him with guitarists Billy Burnette and Rick Vito. The new lineup of the band recorded their first album, Behind the Mask, in 1990. It became the band's first album since 1975 to not go gold. Following its supporting tour, Nicks and Christine McVie announced they would continue to record with the group, but not tour. Vito left the band in 1991, and the group released the box set 25 Years -- The Chain the following year. The classic Fleetwood Mac lineup of Fleetwood, the McVies, Buckingham, and Nicks reunited to play President Bill Clinton's inauguration in early 1993, but the concert did not lead to a full-fledged reunion. Later that year, Nicks left the band and was replaced by Bekka Bramlett and Dave Mason; Christine McVie left the group shortly afterward. The new lineup of Fleetwood Mac began touring in 1994, releasing Time the following year to little attention. While the new version of Fleetwood Mac wasn't commercially successful, neither were the solo careers of Buckingham, Nicks, and McVie, prompting speculation of a full-fledged reunion in 1997. Soon these whispers proved to be true, as the classic Rumours quintet reunited for a live performance that became the 1997 album The Dance. The album performed well, debuting at number one on Billboard and generating an adult contemporary hit in the new version of "Landslide." Fleetwood Mac supported The Dance with a tour that lasted throughout the year and, early in 1998, the band was inducted into the Rock & Roll Hall of Fame. Not long afterward, Christine McVie announced she was leaving the band.

Her departure may have slowed the speed of Fleetwood Mac's reunion, but the remaining quartet set to work writing and recording a new album. The resulting Say You Will appeared in April of 2003; it was their first studio album in eight years and the first in 16 to feature Buckingham and Nicks. Say You Will performed well -- it went gold in the U.S., U.K., and Canada, with the singles "Peacekeeper" and "Say You Will" reaching the U.S. Adult Contemporary Top 20 -- and the accompanying international tour was a success. After a few quiet years when Buckingham resumed his solo career and the group unsuccessfully courted Sheryl Crow as a replacement for Christine McVie, they reconvened for a tour in 2009. Four years later, the group celebrated the 35th anniversary of Rumours with a new deluxe box reissue accompanied by a tour. As the tour got underway in April, the band unexpectedly released a four-track Extended Play of new material; it received good notices and entered the U.S. charts at 48.

During a three-night stint at London's O2 in September 2013, Christine McVie appeared with Fleetwood Mac for the first time in 15 years. In January 2014, the band announced that Christine was rejoining the group and they started recording a new album. The progress on the album was slow and steady, partially due to individual solo projects, partially due to interruptions caused by the band's ongoing world tour; they played international dates in both 2014 and 2015. As the group continued to chip away at their new record, they released a Super Deluxe reissue of Tusk in time for the holidays of 2015, which was followed the subsequent fall by a Deluxe reissue of Mirage. Further catalog reissues followed in the next few years -- Tango in the Night received a Super Deluxe treatment in 2017, while their eponymous 1975 album got an upgrade in early 2018 -- but the bigger news in Fleetwood Mac circles was Buckingham and McVie recording a duet album together in 2017. Initially planned as a new Fleetwood Mac album, the 2017 set -- entitled Buckingham McVie, echoing 1973's Buckingham Nicks -- turned into a Lindsey and Christine project once Stevie Nicks decided to concentrate on her solo career. Retaining Mick Fleetwood and John McVie as their main rhythm section, Buckingham and McVie finished the album with the assistance of producers Mitchell Froom and Mark Needham, releasing the record in June 2017.

Early in 2018, Fleetwood Mac reunited to play a gig celebrating their award as MusiCares Person of the Year. This turned out to be the last concert Buckingham would play with Fleetwood Mac. In April, Buckingham was fired from the band; he would later file a lawsuit against the group regarding his dismissal. Fleetwood Mac hired Neil Finn and Mike Campbell to replace him and launched an international tour in September 2018, releasing a compilation album titled 50 Years: Don't Stop as a companion to the tour. The record debuted at 12 on the U.K. charts and 65 on Billboard's Top 200. The concert album Before the Beginning: Rare Live & Demo Sessions 1968-1970 arrived in November 2019 and featured previously unreleased live performances captured during Peter Green's time with the band. This reminder of Green's glory days came only months before he died in his sleep on July 25, 2020, at the age of 73. Two months after Green's passing, the box set Fleetwood Mac: 1969-1974 appeared; it had expanded and remastered versions of all the albums the group released during those six years. Christine McVie died on November 30, 2022, after a brief illness; she was 79 years of age. ~ Stephen Thomas Erlewine
