I'm honestly amazed Minnesota is getting a gig--at a new amphitheater about 45 minutes outside of the usual Minneapolis/St. Paul area they've been doing the last several tours. I haven't looked at the numbers, but I think the only show they sold out was the BOS Tour, with smallish-but-noticeable declines since. After being habitually skipped for 15 years straight, though,, I'm not complaining.
The new venue looks to seat an extra 1,500ish over the Xcel Center they've done the last few times, but I imagine they're counting on the package tour with Megadeth and Anthrax to sell better than they have on Legacy and TFP, plus it being a classic hits tour.
