I only discovered IS when they were announced on the roster for this year. I can't believe what I've been missing. *
Got the 2 newer albums back around March from Laser's Edge, I think, and I hope to buy the rest directly from the band if they have a table at the venue. I'm hoping that puts a little bit more money in the bands' pocket than if I had gone ahead and bought them all from an online vendor. If IS doesn't have a table of their own, I'll be downstairs buying from vendors, of course, if they have them in stock.

* always the disclaimer about how I could be oblivious to well-known bands, lol. Only my 2nd progpower coming up here. I'm only about 2 and a half years back into buying new metal. I gave up pretty much on all new music in disgust after Nirvana/alternative came along and Metallica and Queensryche fell off the map. I figured I was stuck with my good old classic metal over and over for the rest of my life. Never knew what was happening in Europe, lol.
So, consequently, I have 15 years or so of yummy back catalog I get the joy of learning about. It never ceases to amaze me what's been out there forever that I didn't know existed.
