It's my favourite, by a long margin. Somehow, Jimmy Page just gets how to nail funky and rock n roll on this one. Not the best performance by Plant. John Paul Jones' bass performance is sublime, as is his use of mellotron and keys. Is this the first time they split guitar tracks in stereo? I hear the 6 string in my right ear and the 12 in my left. Definitely a ground breaking album. Better than IV in my opinion. Discuss.
