Fleetwood Mac

Initially a British blues group, they later shifted towards high-quality pop-rock with the arrival of the American duo Buckingham-Nicks. This change allowed them to remain in the Guinness World Records for five years for the sales record of "Rumours." The lineup, in addition to the rhythmic foundation provided by drummer Mick Fleetwood and bassist John McVie, includes pianist, songwriter, and singer Christine Perfect McVie, guitarist, songwriter, and singer Lindsey Buckingham, and singer-songwriter Stevie Nicks.
