Sounds like an awesome show. This was actually on my list of possibilities, since my wife's family is from the Chicagoland area, but alas it wasn't meant to be. I was camping in the woods with my son last weekend instead.
I also wish I could have gone to MDF for at least one day this year, like I did for Bolt Thrower a few years ago. I would have loved to have seen Autopsy with Absu, Dying Fetus, Eyehategod, Agalloch and all the other bands on Thursday night.
Like someone else said, ending the set with three songs from Severed Survival
is awesome, although I can't see how they skipped over "Service for a Vacant Coffin" altogether. That shit is just nuts.
Still awesome though. Lucky Chicago bastards.
