This is Swedish House Mafia at the iheart radio festival on September 21st, 2012 in Las Vegas. The person shooting this video is easily 100-150 ft back from the stage yet has an almost perfect view of the concert.
Before you buy your tickets you should consider that the 'One Last Tour' stage set up is designed for huge arenas, meaning there will most likely not be a bad seat at the Bell Centre or Rogers Centre. If you get too close to the stage you might get a pixelated view of the light show while not being able to see the Swedish House Mafia because they are hoisted up on an elevated platform.
If I were buying tickets for this event I'd probably try for the middle rows of the 1st level which will probably give me the perfect viewing angle without having to pay premium for floor access. But that's just me.
Montreal, Bell Centre: I'd buy the $83 tickets in the Red B General Admission where I'd get a perfect front view of the stage.
Update: Early ticket sales are in: the Amsterdam show sold out but a 2nd show was almost immediately added. Could they be planning the same thing in Toronto and Montreal as well? There is a lot of days in between Feb 23rd and Feb 27th for a possible 2nd show in each city.
