who plays the harmonica on when the levee breaks
When the Levee Breaks Page and John Paul Jones based their guitar and bass lines on the original song.[12] However, they do not follow its twelve-bar blues I–IV–V–I structure, but instead use a one-chord or modal approach to give it a droning sound.[1] Plant uses many of the lyrics, but takes a different melodic approach.[13] He also adds a harmonica part; when mixing, a backward echo effect was created, whereby the echo is heard ahead of the source.[11]
