4.5 Underrated. TheRockstar77 | 22/05/2011 | See all TheRockstar77's reviews (6) This is a very powerful & emotional album. You can feel Robert Plant singing with all his heart. It was never going to be easy to follow Physical Graffiti, it's like Led Zeppelin wrote this album for themselves. A heavy rock and blues vibe which of course is what Zep do best.A truly wonderful heart-felt album.
