Awesome dude.
I will tell you, you will NOT be disappointed.
I first saw Dream Theater last august on my 20th birthday. Greatest single day of my life (so far)
Everything was great. I managed to meet Mike Portnoy earlier in the day at a meet and greet at CASICO Interstate Music, and got some stuff autographed (one being my right arm!) and got a pic with him. I then went to the show and got to meet the band and everything. Got a buncha pics of that, as well as the opportunity to mingle with the band and talk to each member. I then got to see them front row later on that night with a bunch of my friends who had come along.
Here are some pics I have from that day…
I am hopefully going to see them again later this month on the Progressive Nation tour in Chicago.
