I first saw TSO back when they were still called Savatage, and I would say that a casual look is deffinately appropriate. Keep in mind that they are a metal band, after all- at least, the Savatage part! (On a side note, as a fan of these guys since Hall Of The Mountain King, I still haven't gotten used to seeing them in tuxedos!) Enjoy the show. I missed them this year. They never make it here before Thanksgiving! I went to see when they were coming and found that they had already been and gone. That's the second show I've missed this year in that way. The first was Dream Theater. Ah well... Such is life.
