Concerts and live performances you've seen

I'm sure your yells brought Red Eyes and Tears to their sound technician. 

I'd hope so. ;P
I lost my voice for a couple days after the Foo's concert.
For Iron Maiden, I got a great spot, not right up close (I was a broke student at the time) but I was right up the front of the mid section, so still reasonably close to the stage, and we were right by the speakers, so I couldn't hear well for a couple days after xD

I've noticed in Asia they don't play as loud. Iron Maiden is the only band I've seen in both Canada and China, and they were much louder in Canada.
