I miss Milwaukee Metal Fest. I only went once (got to see Death) and had a ton of fun. Maryland Deathfest is about the closest thing you'll get to a fest similar to the ones in Europe but even that pales in comparison to the open air fests like Wacken or Hellfest.
The last deathfest I went to was when they still had it inside I think Nuclear Assault was the big headliner. I'd like to go to Prog Power but that shit sells out in a second! Need more folk/black/power metal bands but since no one really likes that stuff in America its never going to happen.
