Cygnus, (Cygnus X1??)
I've seen RUSH live at least 12 times! Great shows, but you are right about lacking charisma. The problem is that the whole show is carefully timed. I had the privilege of being behind the stage at Maple Leaf Gardens a few years ago, and I saw the computers in action. If you see them 2 nights in a row you'll see 2 exact shows, including very brief comments occasionally. The quality of the music though is phenominal!
BTW, there is a new CD from them coming out next year. Personally, I'm looking forward to it.
