While drummer Mick Fleetwood and bassist John McVie have anchored Fleetwood Mac's rhythm section since its late-'60s origins, the band had several incarnations — generally defined as the Peter Green/Jeremy Spencer blues era and the Bob Welch California pop era — before its most successful lineup crystalized with singer/keyboardist Christine McVie, singer/guitarist Lindsay Buckingham, and singer Stevie Nicks. The cross-Atlantic, blues/pop/rock 'n' roll textures the quintet brought together, fueled by the tensions of two simultaneously imploding relationships (the McVies and Buckingham-Nicks), formulated the volatile chemistry that inspired one of the most enduring rock albums of the era, 1977's Rumours. Minus Christine McVie, who retired in the late '90s, the remaining classic Mac quartet is touring again on the 35th anniversary of Rumours, which has been reissued by Rhino with additional outtakes and live material. The current shows focus on Rumours and the lineup's additional nuggets, while reportedly still heavily mining the remnants of the Buckingham-Nicks romance. Yesterday may be gone, as the song says, but Fleetwood Mac is still definitely here.
