I've seen all of my top 5 bands live too, several times each, with the exception of Metallica, which I will be seeing in May
I went to see Tool last year because the hubby is a big tool fan and I have to say, it was a unique show. Maynard performed the entire set on this revolving pedestal, which was set off towards the back of the stage, and he was wearing only a pair of black underwear. LOL Hopefully you'll get to see Tool soon.
