You're lucky - I have never seen Tool in concert. I hope that they expand their 10,000 Days tour to include a city near me such as Ottawa (where I work) or Montreal. My brother has seen them and he says that their shows are almost ethereal.
I have been fortunate to see Rush several times, beginning with the "Moving Pictures" tour in 1981. It is always a sensory overload - one that you should check out if you haven't already. You obviously have great taste in music!
On a happy note - I scored a pair of Police tickets to the July 25 show in Montreal. They're in the nosebleeds, but I'll be there! Who would have thought that 23 years after breaking up, they'd get back together? The whole Eagles "Hell Freezes Over" thing pales in comparison to this reunion! The ironic thing is that Best Buy mailed me a presale code for the July 26 show which was announced yesterday. I could surely get better seats for the second show but I want to be there on opening night.
