Not that it matters this much but this is my AA experience:
Firstly, I got to see amon amarth in November I believe, I met the band and got my ticket signed (I apologize for bugging you guys while you were getting some food though! Thanks for the autograph and the handshakes)
Basically, everyone was stoked about AA. Noone was really there yet, maybe 300 people, but everyone that was there was into it so it didn' really matter.
Trivium came, I went to go sit around and avoid metalcore kiddies. I witnessed a mass exodus, nearly all the people who were upstairs for the AA set were leaving. I'm dead serious, I saw over 100 people walk out. I asked some of them before they left and basically got "Already saw the band I came to see"
Now, I don't mind people walking out on trivium or bodom (I left 20 minutes into bodom, I didn't even watch trivium.) but I do mind promoters wasting people's money. I'd pay $20 to see AA and have them play a longer set, Hell, I paid my $20 just to see amon-fucking-amarth. But damn.
They rocked my face, though.
An I gave those bodom kiddies a roughing up, chanting their candyassed 'bodom! bodom! bodom!' To which I reply "Screw you pussies, Amon Amarth!"
I guess everyone thought it was funny
