How was it? (the concert)
Dream Theater's set was too short and too early (still light out), but the weather was perfect (80's and overcast, last week we were in the 100's) and DT were great. Even LaBrie hit all the right notes, though he started the concert with "Houston!... Dallas!".... Not too many DT fans there.
As for Iron Maiden, I was never a fan but was looking forward to it. Overall, they are high energy, but I wasn't impressed. Way too monotonous for me, and I couldn't even tell the songs apart. Everyone else seemed to enjoy it though.
