Fleetwood Mac will release an expanded version of 1979 album Tusk on December 4.
The double-length work was a departure from highly successful predecessorRumours, and it was the most expensive album recorded up to that point, costing over $1m to produce.
The deluxe edition contains five CDs, a DVD and two vinyl discs, which offer the original remastered album, unheard session recordings plus singles, demos, remixes and and live tracks.
Tusk will also be available in 3CD and single-disc editions.
