While Fleetwood Mac have been around for more than 40 years, most remember their output after 1975, when Stevie Nicks and Lindsey Buckingham joined the band. That classic 'Rumours' era was the band's most successful, but equal attention should be given to the band's early years, when Fleetwood Mac were a fledgling blues band.

In 'Fleetwood Mac -- Unbroken Chain,' the band's full legacy is explored with fans, peers and former members all weighing in. Starting with founder Peter Green's origins in John Mayall and the Bluesbreakers (where he replaced a young Eric Clapton) to the band's post-'Rumours' turmoil and eventual reconciliation, the documentary is the ultimate guide to the fab five's past, present and possible future.
