Host, Garage to Stadiums Music History Podcast
How did Fleetwood Mac’s sound evolve? The band began in 1967 as a British blues group led by guitarist Peter Green, shifted toward melodic rock during the early 1970s, and then blended California folk rock, pop and rock after Stevie Nicks and Lindsey Buckingham joined in 1975.
Fleetwood Mac’s transformation was not one sudden reinvention. Each lineup introduced new songwriters and musical influences, while Mick Fleetwood and John McVie provided a rhythmic foundation that connected the band’s very different eras. Peter Green supplied its blues intensity, Christine McVie and Bob Welch moved it toward melody and harmony, and Buckingham and Nicks helped create the polished but emotionally volatile sound that made the band globally successful.
Mark Blake, author of Dreams: The Many Lives of Fleetwood Mac, draws on extensive interviews with Mick Fleetwood, Stevie Nicks, Lindsey Buckingham, Peter Green and Christine McVie to examine how changing personalities, relationships and musical ambitions repeatedly transformed the band’s sound.

What Genre Is Fleetwood Mac?
Fleetwood Mac cannot be classified as one genre because the band’s musical identity changed dramatically across its history. Its music has included British blues, blues rock, melodic rock, folk rock, soft rock and pop rock.
These changes were driven largely by the musicians and songwriters who entered and left the band. Peter Green established its blues foundation. Christine McVie and Bob Welch introduced a more melodic and harmony-based approach. Lindsey Buckingham and Stevie Nicks then brought contrasting strains of California rock, folk and pop.
Despite these transformations, Fleetwood Mac retained important elements of continuity. Mick Fleetwood’s spacious drumming and John McVie’s economical bass playing gave each lineup a recognizable rhythmic foundation. Christine McVie’s songwriting also helped connect the transitional early-1970s period with the band’s later commercial peak.
Fleetwood Mac’s musical evolution can therefore be understood through three distinct eras, each of which reshaped the band without completely erasing what came before.
How Did Fleetwood Mac Begin as a British Blues Band?
Fleetwood Mac formed in England in 1967 during the British blues boom. Young British musicians were discovering Black American artists such as Muddy Waters, Howlin’ Wolf, Sonny Boy Williamson and Buddy Guy, whose records were difficult to obtain and rarely heard on British radio.
As biographer Mark Blake explained on the Garage to Stadiums Music History podcast, part of the blues’ appeal in Britain came from its scarcity. “It was difficult music to get hold of, and it was seen as authentic.” Because the records received little radio exposure and often had to be imported, discovering this music gave young British musicians the sense that they were uncovering something largely ignored by the mainstream.
Guitarist Peter Green founded Fleetwood Mac with the intention of creating a Chicago-style blues band. He named the group after drummer Mick Fleetwood and bassist John McVie, reportedly believing that a band named after its rhythm section could continue even if he eventually left. That decision would prove remarkably prophetic.
Fleetwood Mac quickly developed a reputation as a loud and powerful live act. The band released two studio albums in 1968, both rooted largely in traditional blues. Green’s expressive guitar playing placed him alongside Eric Clapton as one of Britain’s leading blues guitarists, but he soon became restless with the limitations of the form.
As Blake explained on the Garage to Stadiums Music History podcast, Green was already pushing Fleetwood Mac beyond conventional blues by late 1968. The instrumental “Albatross” was atmospheric and restrained, while “The Green Manalishi (With the Two Prong Crown)” was dark, heavy and psychologically unsettling. The contrast between those recordings showed that Fleetwood Mac’s first major transformation had begun before Green left the band.
Blake emphasized the magnitude of Green’s departure: “At the peak of their success, just as they’re starting to make money, they lose him, and he is the primary songwriter, the primary force in the band.” Fleetwood Mac was therefore not merely changing guitarists. It was losing the musician who had created its original identity.
Green's declining mental health eventually overwhelmed his ability to continue. Psychedelic drug use may have intensified his existing difficulties, although the popular story that a single experience in Munich entirely caused his breakdown oversimplifies what happened. When Green departed in 1970, Fleetwood Mac lost its founder, principal songwriter and defining guitarist just as the band was moving beyond its original blues identity.
That crisis ended Fleetwood Mac’s first era, but it also established a pattern that would define the group: the departure of a central creative figure created space for another version of the band to emerge.
How Did Fleetwood Mac’s Sound Change in the Early 1970s?
Fleetwood Mac’s sound changed during the early 1970s as the band moved away from British blues and toward melodic, atmospheric rock. This transitional period is frequently overlooked, but it created the musical bridge between Peter Green’s band and the commercially successful lineup that emerged in 1975.
The transition was anything but orderly. Guitarist Jeremy Spencer abruptly disappeared during an American tour in 1971 and was discovered to have joined the religious group Children of God. Danny Kirwan remained an important guitarist and songwriter but was dismissed in 1972 as his behaviour became increasingly unpredictable. Fleetwood Mac continued replacing key members while trying to preserve a recognizable musical identity.
Christine McVie, formerly Christine Perfect of the British blues band Chicken Shack, became increasingly important after marrying John McVie and officially joining Fleetwood Mac. Her piano playing, restrained vocals and melodic songwriting softened the band’s blues foundation without completely abandoning it.
Blake described this as “the forgotten Fleetwood Mac.” He acknowledged that the albums were not always cohesive, but argued that they contained important material that deserves to be rediscovered. This period matters because it shows Fleetwood Mac gradually assembling the melodic and atmospheric qualities that would define its later success.
American guitarist and songwriter Bob Welch brought another important influence. His dreamlike compositions and West Coast perspective helped move Fleetwood Mac toward the American market. Songs such as “Future Games” and “Hypnotized” reflected a more spacious and introspective style than the band’s original blues recordings.
Danny Kirwan’s “Sands of Time” also revealed the growing importance of layered vocals and atmosphere. Although the musical difference between this period and the later Rumours lineup is substantial, the harmonies, melodic songwriting and polished arrangements were already beginning to take shape.
As Mark Blake explained, Welch and Christine McVie became vital creative forces during a period when Fleetwood Mac had largely disappeared from public attention in Britain but was gradually building an audience in the United States. These albums were not major commercial breakthroughs, yet they allowed the band to evolve rather than become trapped by its earlier identity.
By 1974, Fleetwood Mac was no longer principally a British blues band. It had become an increasingly American-focused rock group built around Mick Fleetwood, John McVie and Christine McVie. The band still needed another creative catalyst, but much of the foundation for its later sound was already in place.
How Did Stevie Nicks and Lindsey Buckingham Transform Fleetwood Mac?
Stevie Nicks and Lindsey Buckingham transformed Fleetwood Mac by adding two distinctive songwriters, a more contemporary California sound and a creative tension that complemented Christine McVie’s melodic pop writing. The resulting five-member lineup turned a respected but commercially inconsistent band into one of the dominant groups of the 1970s.
According to Blake, their discovery began with an extraordinarily fortunate chain of events. A chance encounter while Mick Fleetwood was grocery shopping led him to visit Sound City Studios in Los Angeles.
At the studio, producer Keith Olsen played Fleetwood “Frozen Love,” a recording by Buckingham Nicks, to demonstrate the recording equipment. Fleetwood was particularly impressed by Lindsey Buckingham’s guitar playing. When Bob Welch subsequently left Fleetwood Mac, Buckingham was approached as a possible replacement. He agreed on the condition that Stevie Nicks join as well.
Fleetwood was particularly impressed by Lindsey Buckingham’s guitar playing. When Bob Welch subsequently left Fleetwood Mac, Buckingham was approached as a possible replacement. He agreed on the condition that Stevie Nicks join as well, bringing their existing musical and personal partnership into the band.
Buckingham contributed far more than guitar. His arranging instincts, studio experimentation and ability to reshape songs helped give Fleetwood Mac a sharper and more modern sound. Nicks brought a distinctive voice, mystical imagery and emotionally direct songwriting. Christine McVie supplied elegant melodies and a warmer pop sensibility, while Mick Fleetwood and John McVie provided the disciplined rhythm section holding these contrasting styles together.
The self-titled 1975 album demonstrated how effectively the new combination worked. Nicks contributed “Rhiannon” and “Landslide,” while Christine McVie wrote “Over My Head” and “Say You Love Me.” Rather than sounding like three unrelated songwriters, the band used vocal harmonies, Buckingham’s arrangements and the Fleetwood-McVie rhythm section to create a coherent musical identity.
This was the central achievement of the celebrated five-member lineup. Fleetwood Mac did not depend on one dominant writer or one fixed style. Its sound emerged from the contrast among Buckingham, Nicks and Christine McVie, with each member reaching listeners in a different way.
What Happened Between Stevie Nicks and Lindsey Buckingham?
Stevie Nicks and Lindsey Buckingham met as teenagers and first sang together at an after-school gathering. They later performed in the band Fritz before becoming both a couple and the musical duo Buckingham Nicks. Their 1973 album failed commercially, leaving Nicks working as a waitress and house cleaner while Buckingham concentrated on writing and recording.
They joined Fleetwood Mac together in 1975, but their relationship was already under strain. Nicks later said they were moving toward separation even before entering the band. Fleetwood Mac’s sudden success increased the pressure, forcing them to work together while their romantic partnership deteriorated.
Blake saw their creative differences as essential to the partnership. Nicks supplied poetic ideas, unconventional phrasing and emotional ambiguity, while Buckingham helped shape her material into carefully constructed recordings. Her melodies and lyrics did not always conform to the structures Buckingham expected, but songs such as “Dreams” proved that her instincts worked precisely because they resisted those rules. Their personal incompatibility became part of their creative chemistry.
How their breakup shaped Rumours
By the time Fleetwood Mac began recording Rumours, Nicks and Buckingham were separating, John and Christine McVie’s marriage was ending, and Mick Fleetwood’s marriage to Jenny Boyd was also collapsing. The relationships had ended, but the musicians could not escape one another. They still had to write, record, harmonize and tour together.
Blake recalled Christine McVie telling him that they were not going to let the band fall apart over something “as trivial as a divorce.” The remark captures the unusual priority within Fleetwood Mac: preserving the band mattered more than escaping the personal conflict inside it.
That commitment created an extraordinary recording environment. Nicks and Buckingham could sing closely blended harmonies into the same microphone, then resume arguing as soon as the recording stopped. Their ability to convert hostility into performance became one of the defining characteristics of Rumours.
The album’s songs often functioned as competing accounts of the band members’ relationships. Nicks wrote “Dreams” as a measured response to Buckingham, urging him to accept the breakup and move forward. Buckingham answered with the more accusatory “Go Your Own Way,” including a line about “shacking up” that
Nicks strongly resented.
Christine McVie wrote “You Make Loving Fun” about her new relationship with Fleetwood Mac’s lighting director while she was still performing alongside John McVie. Gold Dust Woman” captured the darker atmosphere surrounding the sessions. Nicks has offered different explanations of the song over the years, including its connection to drugs, but its sound reflects the emotional exhaustion and excess surrounding the band.
“The Chain” provided the album’s clearest statement about the band itself. Constructed from contributions by all five members, it acknowledged that their personal relationships were breaking while insisting that the musical bond could survive. Its central idea, that the chain could not be broken, became Fleetwood Mac’s declaration of collective endurance.
The achievement of Rumours was therefore not simply that personal turmoil inspired successful songs. Fleetwood Mac transformed several conflicting perspectives into one coherent album. The musicians were not merely describing their breakups after the fact. They were performing those songs with, and sometimes directly at, the people who had inspired them.
How Did Fleetwood Mac Reinvent Its Sound After Rumours?
It should explain how Buckingham resisted making another Rumours, incorporated punk and new-wave ideas, and pushed the band toward the experimental sound of Tusk. The 1979 album is widely recognized as a deliberate departure from the polished sound of its predecessor.
That is the only substantial content gap. Once we add that section, the legacy conclusion will feel earned rather than arriving immediately after 1977.
Why Does Fleetwood Mac’s Musical Legacy Endure?
Blake identified an unusual continuity beneath Fleetwood Mac’s dramatic transformations. “There’s this sort of weird thread that runs through” the band’s different eras, he observed, adding that there is “a unity to everything they did somehow.”
He attributed part of Fleetwood Mac’s uniqueness to having three strong songwriters who could all produce hits, along with two women who were central creative figures rather than supporting performers. Christine McVie and Stevie Nicks wrote and sang their own material, while Christine was also an accomplished instrumentalist.
That combination allowed Fleetwood Mac to cross boundaries between blues, rock, folk, country and pop. Blake argued that its influence remains audible across contemporary music because Rumours “hasn’t dated.” The band’s personnel and sound repeatedly changed, but its best music retained an emotional directness that survived every transformation.
