Fleetwood Mac - The five albums that came out before they 'sold out' with those overplayed but still good albums. Namely: Future Games, Bare Trees, Penguin, Mystery to Me, and Heroes Are Hard To Find. Under-rated, varied stuff here for you guys into 1970s music. Bob Welch especially, with all his supernatural / paranormal themes in many of his songs.
A shame most people only know two versions of this band.....the preceding Peter Green era, and the successor Nicks/Buckingham era.
