(story of a song 3/3)
From 1969, this song has one of the best guitar solos ever. The free-form section was the result of Page and engineer Eddie Kramer "twiddling every knob known to man."
Some parts of the song as well as some lyrics were borrowed from a song called "You Need Loving" by the Small Faces. The Small Faces was a '60 band that Zeppelin modeled themselves after.
Also, this might be the first use of "backward echo." Page put the echo of Plant's lines before he says them, creating an interesting sound.
