This albumn is frequently considered to be a watershed event in Rock 'n Roll. Give the credit to Jimmy Page who concieved this sound and put this band together on the fly.
Considering the impact this record had, it's chronology is rather amazing. Zeppelin was formed under the auscpices of finding new members of the Yardbirds, who were still a working band. Original members Kieth Relf and Jim McCarty quit the band in July of '68. Until August, Yardbird Chris Deja was to be a member of the band. Deja and Page had no clue as to who they wanted to replace the old Yardbird members. They went after Steve Marriot of Small Faces to sing. He reccomended another singer who reccomended 19-year-old Robert Plant. Deja and Page hired Plant who reccomended Jon Bonham to play the drums, whom they also hired. In mid-August, Deja quit. Page hired John Paul Jones, an associate from his session days to play bass and keyboards.
The Yardbirds had concert obligations which the new band had to fulfill. Their first concert was Sept. 7th. They recorded this albumn in mid-October in only 30 hours. The next month they embarked on a U.S. tour.
Page's 2-year stint with the Yardbirds was an uninspired period. Page as a creative force seemed to pale vs. his predeccessor, Jeff Beck. So how did this albumn come about? It's like nothing the Yardbirds, who were entrenched in quasi-psychadelia, were doing a the time. Page went back to the raw blues sound of the early Yardbirds, but added guitar dynamics of the Hendrix, John McGlaughlin era. That he was able to find Plant and Bonham, whose power was so well suited for Zeppelin, in two weeks, is astonishing.
