Where's This Concert Venue!!!!?

So I want to go to the Asking Alexandria concert in Edmonton, AB CANADA on April 2nd 2011. but when I go to buy tickets at the link below, if I go to the ticketmaster link, it says the concert is at the Edmonotn Events Centre which is at West Edmonton Mall in the west end. But when I go to the band's official website, it says the venue is at Avenue Theatre, which is on the other side of the city!!! where should I get my tix from, and WHERE THE **** DO I GO FOR THE CONCERT??? THANKS.
