Originally a British blues outfit, Fleetwood Mac quickly morphed into one of the biggest superstar rock bands on the planet in 1975 and remained so through the decade's end when Lindsey Buckingham and Stevie Nicks joined founding members Christine and John McVie and Mick Fleetwood. Transplanted to L.A., the realigned group's eponymous inaugural album hit number 1 and sold five times platinum previously, no Fleetwood Mac album had climbed higher than number 34. The follow-up, 1977's Rumours, an irresistible tour de force documenting the band's personal turmoil, shattered all existing records and remains the sixth-biggest-selling album ever. Along with 1979's artistically pioneering Tusk, this trio of masterpieces showcases the pop-rock icons at their creative zenith.
