I know this is an old post but I just got back from seeing Tool live. All I can say is that if you have not seen them live you should before you start to trash them. Nearly everyone (and I mean everyone!) stood for the entire 2 hour performance including this old man. They were awesome! Yes they had a great light show and graphics, but they were all about the music. They stood up there and just kicked you in the nads.
I would go see them over every other band mentioned in this thread (especially since I haven't heard of half of them) they were that good live.
Hey but this is just my ever humble opinion!
