who is in a position to know -- 30 shows in North America are on pace for sellout business even though they won't play until June and July. Furthermore, not only are hip-hop/R&B shows historically known to be late-selling, the entire live business has trended more to a late-buying sales pattern during the economic downturn.
Just earlier this week, the New York Post's Page Six reported that Rihanna's Roc Nation manager, Jay Brown, advised her to cancel domestic dates of the tour. Still, Rihanna has already sold out 56 arenas in Europe.
Roc Nation, a Live Nation affiliate, is the management company for Rihanna. She's booked by Cara Lewis at William Morris Endeavor Entertainment.
