I just was glancing at Blabbermouth.net and I noticed that there were Metallica tour dates up. I know most University of Iowa students are either from Illinois or Iowa, so guess what?
There is one stop in Des Moines, Iowa, a stop in Moline, Illinois right on the Iowa/Illinois border and a stop in Chicago, Illinois.
See the tour date section for the exact dates and information. Hell yeah!
Oh, if you are wondering all dates near Iowa/Illinois are with Down and The Sword as openers. Except for the Chicago show that is. Machinehead in place of Down.
UPDATE: Check out this video of Metallica doing a Mercyful Fate medley, with the almighty King Diamond himself!
