Still plenty of tickets left, but I wouldn't call it "empty." Highly unlikely that they would cancel at this point. It looks like there are about 1,600 tickets left, not including floor GA which must be mostly sold since there have been periods when only resale were available for floor. Capacity is reported to be 17,560, so this makes the show over 90% sold. Hardly a disaster. I'm just hoping for a good, lively crowd. I don't think some empty seats will discourage the band from putting on the best show they can.
