I ordered the blu-ray, got it earlier this week and finally had a chance to watch it today. These guys still rock, and I just boggle that so much sound - so many layers of sound - is just coming from four guys. Plant doesn't have the range he used to and it shows on a few songs (and really only because everyone's heard the original recordings and his highs are so damn noticeable that their lack is equally noticeable), but he still sounds good and you can get a sense of that Golden God stage presence. Page tears it up all night long. John Paul Jones is just some inhumanly talented musical monster. And Jason really nails the drums - he's got his father's chops and he's got the sound down pat. Only thing maybe is that he's using a double-bass pedal to do some sections his dad did with one foot, but his father had some crazy technique that modern drummers would have no reason to develop, and that's not something you can just learn in six weeks. The highlight for me was Kashmir. Probably my favorite Zeppelin song anyways, but it's just transcendent seeing them do it live. They're up there, and they're playing and it's just hitting you and you don't know where it's beginning or ending and it doesn't really matter. It's just energy ebbing and flowing for seven or eight minutes straight.
