The last time Rihanna was scheduled to perform in Washington state, it was 2010, she was plotting out her Last Girl on Earth tour, and she’d booked the White River Amphitheatre as the tour kickoff. A few days before the show, she canceled–the official word vaguely blamed “production changes,” but rumor had it that not enough tickets were sold, and that issue was plaguing other dates on the tour as well–a rumored less than 20% capacity at some venues.In the two years since, though, Rihanna’s become a bigger pop star, reaching the point of ubiquity–her fifth and sixth albums, Loud and Talk That Talk, both sold well and produced massively successful hit singles (“What’s My Name?”; “We Found Love”); she sold out ten nights at London’s O2 Arena, breaking the record for the most sold out shows for a female artist at that venue (her tours have historically always done better in Europe than the U.S.); she was named Esquire’s sexiest woman alive in 2011; she also made history by became the highest-selling digital artist ever.Now Rihanna’s planning out a 2013 itinerary, the Diamonds World Tour, and a Seattle date at KeyArena has been set for April 3. Tickets will be available next week on September 21 for $36.50-$122. KeyArena has a smaller capacity than the White River, but not by much. It’ll be interesting to see how the show sells. I’m predicting a sell out. Pop fans are the ficklest in the world.
