A good old Led Zeppelin classic. Better not to focus too much on the lyrics that are stupid at best, unsettling and disgusting at worst. Great riffing, great drumming, great bass lines, and well, Plant's vocals are what they are you know -- sometimes I find them powerful, sometimes irritating.
Listening to this again, it’s pretty clear that Spinal Tap really wasn’t all that much of a parody. When the opening track bangs on about being a ‘back door man’ giving every inch of his love there isn’t really any doubt about what he’s singing about. We also get a folky song about Gollum making off with the hero’s girlfriend in Mordor which I don’t remember from the books. Oh, and let’s not talk about the drum solo. The remastered version sounds good though
