Wherein Peter Green, main guitar man for the early Fleetwood Mac, lays down a blueprint for a blues rock that aims to move so far beyond the bounds of either blues or rock that a new name will probably be required – something that contains the fierce grit of the Mississippi Delta circa 1930, waters rising, levees about to overflow, but also the majestic sweep of a Ennio Morricone Spaghetti western soundtrack, that scene where the cold eyed killer looks into the mirror and sees something monstrous looking back. Which sadly, is what happened to Peter Green, sort of.  He got swallowed by the monster – the Green Manalishi he called it in another song. Some say it was just money, greed. Others that it was the devil himself. Either way, Mr. Green disappeared down his own nasty psychedelic wormhole, went mad for a while, got lost. As for Fleetwood Mac, they did what any proper blues outfit would do. They played on.
