Fleetwood Mac builds on its formidable legacy as one of rock's most legendary acts as they re-visit their most ambitious album with an expanded edition of 'Tusk.' Originally released in 1979, the Grammy Award-nominated, double-album sold more than four million copies worldwide, climbed to #2 on the Australian album charts, and introduced fans to hits like "Sara," "Think About Me," and the title track. 'Tusk' is considered experimental, primarily due to Lindsey Buckingham's sparser songwriting arrangements and the influence of punk rock and new wave on his production techniques.
