Robert Plant's ability to perform blues songs verges on the genius. In the slow into to this track he actually mimics the natural tremello that was a feature of Sonny Boy Williamsons voice. Have a go yourself - play a copy of Bring It On Home by Sonny Boy Williamson and then play Zeppelin's version. You have, in a nutshell their uniqueness: the ability to persent largely traditional, blues based music in a way that was relevant for their time. Plant was an absolutely magificent vocalist.
