Deep Purple and Aerosmith along with the Rolling Stones, filled Sports arenas all around the world, in an orgy of excess.The Who smashed their amplifiers as they exploded into an attention-seeking heap, not unlike naughty schoolboys, while Iggy Pop buried his Jewishness in an avalanche of broken glass. Good old boy country Rockers such as Creedence Clearwater Revival sang about grapevines and gumbo.The sublimely angelic Jimi Hendrix cut down a mountain with the palm of his hand. For every androgynous David Bowie, there was an equally insensitive Alice Cooper. David Bowie fell to Earth, Bruce Springsteen CAME from the Earth. If Bob Dylan was riding freight cars, then Springsteen was in a speeding, souped up, forties Hudson careening down a Lonesome Highway. Ginger Baker, the drummer from super group Cream was once accused that his band gave birth to heavy Metal, he replying that if he did, then he surely should have aborted it. If anyone did conceive that genre, then the blame must fall squarely on the shoulders of Led Zeppelin, the fathers of Air Guitar, who dragged the sixties beat blues, kicking and screaming into the Seventies, and who even now forty something years later still hold sway and a kind of mythical worship like the Gods of ancient times.
