Chicago's summer/fall Metal shows..who's going to what?

The Amon Amarth tour will be cool. I got too see them open for Nile / Kreator / Vader a few years back and they were great but got like 5 songs. It will be great to see them headline finally. I really hope this isnt a Pearl Room show...I know it will though.
 
Yeah, I just saw Decapitated a few weeks ago. I've been waiting to see Amon Amarth, but I don't want to go to Sounds of the Underground or a Trivium show (last year). Finally they're headlining
 
I am a n00B to Amon Amarth.
I only have a couple songs downloaded, but they are great.
I would possibly check this tour out.

I am sure I have seen Decapitated at Milwaukee Metalfest at one point or another. Not really my genre of expertise though, so I could be mistaken.
