I'd love to say that Symphony X were awesome but I can't. Because they didn't play.
I went to the West Palm Beach show, and because of the rain the whole second stage got wet and Symphony X's performance was canceled. I was about to cry, they were the reason I bought my Gigantour ticket. They all came out onto the set and apologized, it was very unreal to see them in person. Jason said: "I'm sorry guys, the only thing I can do for you right is this:" And he grabbed three water bottles and started juggling them. Hilarious stuff...
At least I got to meet them later at the FYE tent and got my signed copy of "The Odyssey" (which I bought again just for the signing).
Nevermore was awesome. The Symphony X-killing rain started during their set, and they played with lightning and thunder as background. Pretty kickass metal moment. Loomis had orgasmic tone, his solos were awesomely played.
The Dillinger Escape Plan sucked balls. I can't believe those jokers were playing on the fucking main stage while SX was trying to keep their gear from getting wet.
Fear Factory was awesome, they had the best rythm tone; very heavy and defined.
Dream Theater was amazing, Petrucci nailed all his solos, very clean playing. They were too loud though, LaBrie was almost inaudible.
Megadeth was nice, I'm not really a fan.
