Because the information is circulating that the American tour is so badly sold, I took the trouble to look at Ticketmaster to see what the current ticket status is.
I was able to see 24 of the 25 concerts (Quebec no longer). I couldn't get any meaningful information for three of them (the sales system seems to be different). Well.
First of all: None of the shows is sold out. - But:
10 concerts (almost the half) are excellently sold
7 concerts are sold reasonably well (there are gaps, but no yawning emptiness)
4 concerts only are lukewarmly sold (you will see the empty rows)
The start in the North East in Canada is going very well.
The first third of the USA tour is going very well to reasonably well. - The density of stops seems to have been set a little too optimistically, but it's okay.
The West Coast is going very well, the middle so-so.
Two of the three shows in Texas aren't doing well (the third was one with bad info, but also seemed lousy). I guess those three shows in relative proximity to each other - they misjudged.
The Back To Front Tour of America was much more airy set. Maybe it was too airy, they wanted to improve - now it was too daring.
On the whole, however, it doesn't look as if the entire tour will take place in front of empty halls or become a flop.
And maybe the ticket price will be lowered in the poorly selling cities shortly before the date and then something will move. - That remains to be seen.
