This is a great concert. The volume was low but the music sounds as good in this new movie as it does in the old movie, The Song Remains the Same (which I was able to watch on tv when I got home afterwards). It looks like Jimmy used the exact same guitars in both films and he didn't miss a note. Robert can still wail and moan almost as good as ever. John did an excellent job on bass and keyboard. Jason sounds just like his late, great father; I wish they had let him play Moby Dick. You can tell they worked really hard to keep their sound as great as the good old days. I would have liked to see Jimmy play more than a few notes on the theremin but at least he used it a little. The lasers and light show was interesting. Unlike The Song Remains the Same, Celebration Day is only a great concert; it does not include an epic story line woven in between the songs or behind the scenes clips. If you like Led Zeppelin's music, this is a must see!
