Music: The Supernatural - John Mayall & The Bluesbreakers

One could argue that John Mayall & The Bluesbreakers' album, "A Hard Road" was the first pre-Fleetwood Mac album. The band consisted of Peter Green on guitar and bassist John McVie. Drummer Aynsley Dunbar was later replaced by Mick Fleetwood, and thus spawned Peter Green's Fleetwood Mac.
