ICED EARTH CONFIRMED FOR CHICAGO POWERFEST 2008

Everyone is going to suggest something different, but my favs are Night of the Stormrider followed by Burnt Offerings. However, they rarely play those songs live.

Well you can definetly count on hearing "Pure Evil" and possibly Stormrider. Not sure about anything off Burt Offerings.
