" As an artist with that kind of talent and vision emerges , it creates a lot of excitement , and ticket sales worldwide demonstrate that people are really excited to see the show . Over the course of the next many months we 're trying to play to as many people in as many places as possible " , Fogel added . " It 's an across the board home run . " Demands increased and another additional six dates were added to the announced itinerary . The Monster Ball sold out shows in Toronto , Vancouver and San Jose who were compelled to add second dates in each city . In Los Angeles , to ensure that concert goers had the best possible access to tickets , a second performance was announced prior to the onsale of the first shows , and both Staples Center concerts were completely sold out . Billboard estimated that by the time the tour wraps up in 2011 , it would have grossed close to US $ 200 million worldwide .
