Re: The words "Violin" and "rock" shouldn't ever be near each other...
I just got back from seeing TSO live, and I somehow got to get 4th row tickets half an hour before the show started. It was the BEST F***ING CONCERT EVARRRRRR!!!!1!!1!!
Seriously though, it was a great show, the violinists in particular were very impressive. It was worth every penny.
Another band I'd recomend in the same vein as TSO and Apocalyptica is Gregorian, which covers 80's music using Gregorian chanting. It's not only good, but hilarious.
