The likenesses revealed here are undeniable, but so be it. I was aware of most of them except the Taurus-Stairway likeness. I learned of that one via this video, today. Wow. And, I have been a Zeppelin fanatic since 1986!
And, there are still so many unbelievably awesome Zeppelin songs that are wholly original that these influenced numbers should be seen more as tribute to the blues and folk artists they admired, for once Page and Plant found their convolved voice, it was nothing but pure novelty. The fact that they took credit for songs they did not write is pretty shameful, but does not diminish their greatness by one scintilla in my eyes.
In The Light, Ten Years Gone, Kashmir, The Rain Song, The Rover, The Song Remains The Same, Down By The Seaside, Dancing Days, The Immigrant Song: completely original and enough to send them to metal gods Valhalla ten times over.
