Calgary may syphon off a couple of concert dates from Edmonton but a Calgary stop might also encourage more acts to take a swing into Alberta. Vancouver has always had a better concert scene than Edmonton partly to a larger population but also due to its proximity to Seattle. Overall though, the new Saddledome probably won't have much effect as Edmonton has a long and strong history of headbangers supporting its concerts. Still remember standing in line for a couple hours to get tickets for when the Who played the Coliseum back in the 70's. Still have the guitar pick that BB King gave me after a dinner show at the hotel on 105st in the 80's. David Bowie at Commonwealth in the 80's and several times after. The Stones at Commonwealth. Tragically Hip and Midnight Oil at Clarke Stadium. The list goes and on. Not sure if the Kinsmen Field House (probably not) and Myer Horowitz Theatre still host shows but Edmonton has always had a strong concert scene and that's unlikely to change.
